String processing is common in the research field of bioinformatics. However, as the strings that transcoders deal with can usually be extremely large, efficient data structures and algorithms are necessary. Some of these problems are presented as contest problems in ICPC. By mastering the content of this chapter, ICPC contestants will have a better chance at tackling these string processing problems. String processing tasks also appear in IOI, but usually they do not require variables, data structures, or may be simply string manipulations. Additionally, the input and output format tends to be less well-defined than in ICPC problems. IOI tasks that require string processing are usually still solvable using the problem solving paradigms mentioned in Chapter 1. Section 6.1 is drafting for students to solve string problems. Section 6.2 outlines basic string processing skills; however, we believe that it may be advantageous for IOI contestants to learn some of the more advanced material outside of their syllabuses. ## 6.2 Basic String Processing Skills We begin this chapter by listing several basic string processing skills that every competitive programmer must know. In this section, we provide a series of mini tasks that you should solve one after another without asking. You can use your favorite programming language (C, C++, or Java). Try your best to come up with the subtask, unless default implementations do it for you. ### 1. Given a string that only consists of lowercase alphanumeric characters [a-z,0-9], space, and period ('.'), write a program to read the text file from the user — encounter a long string first. When two lines are combined, give the output that the last word of the previous line is separated from the first of the current line. There can be up to 30 of any of your implementations can even give your implementation. Also read and store the last spaces at the end of each line. Note: The sample input file `file.txt` is shown on the next page: After question 1(a) and before task 2. --- (Original document might contain additional tasks or examples; ensure all tasks are addressed as needed.) #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 353 Context:

Grey Areas ![Figure C: Fine engraving, Melancolia I, Albrecht Dürer, 1514.](image_link) 103 ## Introduction This chapter explores the concept of grey areas in various contexts. ### Key Concepts 1. **Ambiguity** - Definition: Ambiguity arises when a statement can have multiple meanings. - Examples: - "I saw the man with the telescope." - "The bank can refuse to lend money." 2. **Context Dependence** - Definition: The meaning of a statement often depends on the surrounding context. - Key Points: - Language is inherently fluid. ### Importance of Grey Areas - Understanding grey areas is crucial in fields such as law, ethics, and interpersonal communication. - It encourages critical thinking and deeper analysis. ### Conclusion In summary, grey areas are an integral part of human understanding and interaction. Recognizing them can lead to more thoughtful discussions and decisions. #################### File: Advanced%20Algebra%20-%20Anthony%20W.%20Knapp%20%28PDF%29.pdf Page: 19 Context:

While we believe that parts of the IOI syllabus have been included in this book, which should give you a respectable base for future IOIs - we are well aware that not IOI books require more problem solving skills and creativity that we cannot teach via this book. So, keep practicing! --- ## Specific to the Teachers/Coaches This book is based on Steven's CS3232 - 'Competitive Programming' course in the School of Computing, National University of Singapore. It is contributed to its teaching teams using the following lesson plan (see Table 2). The PDF slides (only the public versions) can be found in the companion website of this book. This lesson plan contains the various exercises in this book as seen in Appendix A. Fellow teachers/coaches are free to modify the lesson plan to suit your students' needs. | Wk | Topic | In This Book | |----|---------------------------------------------|-----------------------------------| | 01 | Introduction | Chapter 1 | | 02 | Data Structures & Libraries | Chapter 2 | | 03 | Combinatorial Search, Divide & Conquer, Greedy | Section 3.2.4 | | 04 | Dynamic Programming (1: Basic Ideas) | Section 3.2.3 | | 05 | Graphs (1: DFS/BFS) | Chapter 4 | | 06 | Graphs (2: Shortest Paths, Dijkstra) | Section 4.4.5 - 4.17.2 | | 07 | Mid semester break contact | | | 08 | Dynamic Programming (2: More Techniques) | Section 6.3.4 | | 09 | Graphs (3: Max Flow; Bipartite Graph) | Section 6.4.3, 4.7.4 | | 10 | Mathematics (Overview) | Chapter 5 | | 11 | String Processing (Basics, Suffix Array) | Chapter 6 | | 12 | Computational Geometry (Libraries) | Chapter 7 | | | Final exam content | All, including Chapter 8 | **Table 2:** Lesson Plan --- ## To All Readers Due to the diversity of this content, this book is not meant to be read once, but several times. There are exercises that can be skipped at first if the content is too intense at that point of time, but the reader is encouraged to come back and revisit numerous sections when the concepts are more settled. While we strive to present the concepts in this book in a clear, intuitive manner, there are twists we cannot always predict. Make sure to attempt them alone. We believe that this book should lead the aspiring student towards the logical standards as IPC will lead them to the appropriate programming problems. This book is intended for proficient personnel in the field before facing more challenges after mastering this book. But before you assume anything, please check this book's table of contents to see what we mean by "basic". ``` #################### File: A%20MACHINE%20MADE%20THIS%20BOOK%20ten%20sketches%20of%20computer%20science%20-%20JOHN%20WHITINGTON%20%28PDF%29.pdf Page: 80 Context: 66Chapter6.SavingSpaceforawholeclassofdata,suchastextintheEnglishlanguage,orphotographs,orvideo?First,weshouldaddressthequestionofwhetherornotthiskindofuniversalcompressionisevenpossible.Imaginethatourmessageisjustonecharacterlong,andouralphabet(oursetofpossiblecharacters)isthefamiliarA,B,C...Z.Therearethenexactly26differentpossiblemessages,eachconsistingofasinglecharacter.Assumingeachmessageisequallylikely,thereisnowaytoreducethelengthofmessages,andsocompressthem.Infact,thisisnotentirelytrue:wecanmakeatinyimprovement–wecouldsendtheemptymessagefor,say,A,andthenoneoutoftwenty-sixmessageswouldbesmaller.Whataboutamessageoflengthtwo?Again,ifallmessagesareequallylikely,wecandonobetter:ifweweretoencodesomeofthetwo-lettersequencesusingjustoneletter,wewouldhavetousetwo-lettersequencestoindicatetheone-letterones–wewouldhavegainednothing.Thesameargumentappliesforsequencesoflengththreeorfourorfiveorindeedofanylength.However,allisnotlost.Mostinformationhaspatternsinit,orelementswhicharemoreorlesscommon.Forexample,mostofthewordsinthisbookcanbefoundinanEnglishdictionary.Whentherearepatterns,wecanreserveourshortercodesforthemostcommonsequences,reducingtheoveralllengthofthemessage.Itisnotimmediatelyapparenthowtogoaboutthis,soweshallproceedbyexample.Considerthefollowingtext:Whetheritwasembarrassmentorimpatience,thejudgerockedbackwardsandforwardsonhisseat.Themanbehindhim,whomhehadbeentalkingwithearlier,leantforwardagain,eithertogivehimafewgeneralwordsofencouragementorsomespecificpieceofadvice.Belowtheminthehallthepeopletalkedtoeachotherquietlybutanimatedly.Thetwofactionshadearlierseemedtoholdviewsstronglyopposedtoeachotherbutnowtheybegantointermingle,afewindividualspointedupatK.,otherspointedatthejudge.Theairintheroomwasfuggyandextremelyoppressive,thosewhowerestandingfurthestawaycouldhardlyevenbeseenthroughit.Itmusthavebeenespeciallytroublesomeforthosevisitorswhowereinthegallery,astheywereforcedtoquietlyasktheparticipantsintheassemblywhatexactlywashappening,albeitwithtimidglancesat #################### File: A%20MACHINE%20MADE%20THIS%20BOOK%20ten%20sketches%20of%20computer%20science%20-%20JOHN%20WHITINGTON%20%28PDF%29.pdf Page: 149 Context: Chapter10WordstoParagraphsWehavelearnedhowtodesignindividualcharactersofatypefaceusinglinesandcurves,andhowtocombinethemintolines.Nowwemustcombinethelinesintoparagraphs,andtheparagraphsintopages.LookatthefollowingtwoparagraphsfromFranzKafka’sMetamorphosis:Onemorning,whenGregorSamsawokefromtrou-bleddreams,hefoundhimselftransformedinhisbedintoahorriblevermin.Helayonhisarmour-likeback,andifheliftedhisheadalittlehecouldseehisbrownbelly,slightlydomedanddividedbyarchesintostiffsections.Thebeddingwashardlyabletocoveritandseemedreadytoslideoffanymoment.Hismanylegs,pitifullythincomparedwiththesizeoftherestofhim,wavedabouthelplesslyashelooked.“What’shappenedtome?”hethought.Itwasn’tadream.Hisroom,aproperhumanroomalthoughalittletoosmall,laypeacefullybetweenitsfourfamiliarwalls.Acollectionoftextilesampleslayspreadoutonthetable–Samsawasatravellingsalesman–andaboveittherehungapicturethathehadrecentlycutoutofanillustratedmagazineandhousedinanice,gildedframe.Itshowedaladyfittedoutwithafurhatandfurboawhosatupright,raisingaheavyfurmuffthatcoveredthewholeofherlowerarmtowardstheviewer.135 #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 170 Context: # 6.3 AD HOC STRING PROCESSING PROBLEMS © Steven & Felix 1. **UVA 103: Wet Sponge** (read from the left to right) 2. **UVA 104: Pig Land** (find one, similar to UVA 683) 3. **UVA 115: Dead Beaver** (reverse the given format and index) 4. **UVA 117: Awesome Indicators** (indeterminate conversion problem) 5. **UVA 370: Barcodes** (prepare via user’s maps) 6. **UVA 415: Cypher Solver** (pinpoint a rare inverse map) 7. **UVA 556: Crying Kid** (is placed at sky's edge) 8. **UVA 601: Substitution Cypher** (simple character substitution mapping) 9. **UVA 612: Decrypt the Mail** (find matching characters) 10. **UVA 1203: 2-D Bilharphog** (a tensor flow, *'s' != 0, read from bottom) 11. **UVA 1209: Decode the Map** (complete several possible routes for us to consider) 12. **UVA 1210: Find the Elephant** (unidentified problem steps) 13. **UVA 1253: The Vigenère Cypher** (test with QWERTY keys to PYBARI keys) 14. **UVA 1354: I Decoded This** (entire manipulation = Phonatic numbers) 15. **UVA 1361: Decode** (read only the short description, a sublist) 16. **UVA 1167: Parallel Cypher** (block for the description of a tabulator) 17. **UVA 1176: Editorial Routines** (simple display) 18. **UVA 1184: Invisible Hilltops** (filling the description) ##

An abridged edition has been prepared, however, for students who study the subject for only one semester and who do not care to purchase the larger text. It will be observed that the work includes two chapters on solid analytic geometry. These will be found quite sufficient for the ordinary reading of higher mathematics, although they do not pretend to cover the ground necessary for a thorough understanding of the geometry of three dimensions. It will also be noticed that the chapter on higher plane curves includes the more important curves of this nature, considered from the point of view of interest and applications. A complete list is not only unnecessary but undesirable, and the selection given in Chapter XII will be found ample for our purposes. ``` #################### File: Advanced%20Algebra%20-%20Anthony%20W.%20Knapp%20%28PDF%29.pdf Page: 18 Context: # DEPENDENCE AMONG CHAPTERS Below is a chart of the main lines of dependence of chapters on prior chapters.

The ALIGN keyword is used to align the starting address of the corresponding section definition to some predefined multiple of bytes. In the preceding section definition, the sections are aligned to a 4-byte boundary except for the text section. The name of the sections can vary depending on the programmer's will.

The -O binary in the OBJCOPY_FLAGS informs the objcopy utility that it should emit the flat binary file from the object file previously linked by the linker. However, it must be noted that objcopy merely copies the relevant content of the object file into the flat binary file; it doesn't alter the layout of the sections in the linked object file. The next line in the makefile is as follows: build_rom $(ROM_BIN) $(ROM_SIZE) This invokes a custom utility to patch the flat binary file into a valid PCI expansion ROM binary.

Representative transactions | web information retrieval | | | | language model information retrieval | | | Semantic similar patterns | information use; web information; probabilistic information; information filter; text information | In both scenarios, the representative transactions extracted give us the titles of papers that effectively capture the meaning of the given patterns. The experiment demonstrates the effectiveness of semantic pattern annotation to generate a dictionary-like annotation for frequent patterns, which can help a user understand the meaning of annotated patterns. The context modeling and semantic analysis method presented here is general and can deal with any type of frequent patterns with context information. Such semantic annotations can have many other applications such as ranking patterns, categorizing and clustering patterns with semantics, and summarizing databases. Applications of the pattern context model and semantical analysis method are also not limited to pattern annotation; other example applications include pattern compression, transaction clustering, pattern relations discovery, and pattern synonym discovery. ## 7.6.2 Applications of Pattern Mining We have studied many aspects of frequent pattern mining, with topics ranging from efficient mining

TCG Architecture Overview ![Figure 1.3 Steps in comprehending TCG standards implementation in PC architecture](https://example.com/image-link) Figure 1.3 shows that the first document you have to read is the **TCG Specification Architecture Overview**. Then, proceed to the platform-specific design guide document, which in the current context is the **PC platform specification document**. You have to consult the concepts explained in the **TPM main specification**, parts 1–4, and the **TSS document** while reading the PC platform specification document—the dashed blue arrows in Figure 1.3 mean "consult." You can download the **TCG Specification Architecture Overview** at [https://www.trustedcomputinggroup.org/specs/TPM](https://www.trustedcomputinggroup.org/specs/TPM). The TSS document is available for download at [https://www.trustedcomputinggroup.org/specs/TSS](https://www.trustedcomputinggroup.org/specs/TSS), and the PC platform specification document is available for download at [https://www.trustedcomputinggroup.org/specs/PCCLIENT](https://www.trustedcomputinggroup.org/specs/PCCLIENT). The PC platform specification document consists of several files; the relevant ones are: 1. **TCG PC Client–Specific Implementation Specification for Conventional BIOS** - (as of the writing of this book, the latest version of this document is 1.20 final) 2. **PC Client TPM Interface Specification FAQ** Reading these documents will give you a glimpse of the concepts of trusted computing and some details about its implementation in PC architecture. --- Moving forward, I'll explain a bit more about the fundamental concept of **trusted computing** that is covered by the TCG standards. The **TCG Specification Architecture Overview** defines trust as the "expectation that a device will behave in a particular manner for a specific purpose." The advanced features that exist in a trusted platform are protected capabilities, integrity measurement, and integrity reporting. The focus is on the integrity measurement feature because this feature relates directly to the BIOS. As per the **TCG Specification Architecture Overview**, integrity measurement is "the process of obtaining metrics of platform characteristics that affect the integrity (trustworthiness) of a platform; storing those metrics; and putting digests of those metrics in PCRs (platform configuration registers)." I'm not going to delve into this definition or the specifics about PCRs. Nonetheless, it's important to note that in the TCG standards for PC architecture, **core root of trust measurement (CRTM)** is synonymous with **BIOS boot block**. At this point, you have completed the foundational understanding of the TCG architecture and its implications for trusted computing in PC systems. #################### File:

This file contains the definition of a data structure named flashchip. This data structure contains the function pointers and variables needed to access the flash ROM chip. The file also contains the vendor identification number and device identification number for the flash ROM chip that bios_probe supports. • error_msg.h. This file contains the display routine that declares error messages. • error_msg.c. This file contains the display routine that implements error messages. The error-message display routine is regarded as a helper routine because it doesn't posses anything specific to bios_probe. • direct_io.h. This file contains the declaration of functions related to bios_probe device driver. Among them are functions to directly write and read from the hardware port. • direct_io.c. This file contains the implementation of functions declared in direct_io.h and some internal functions to load, unload, activate, and deactivate the device driver. • jedec.h. This file contains the declaration of functions that is "compatible" for flash ROM from different manufacturers and has been accepted as the JEDEC standard. Note that some functions in jedec.h are not just declared but also implemented as inline functions. • jedec.c. This file contains the implementation of functions declared in jedec.h. • Flash_chip_part_number.c. This is not a file name but a placeholder for the files that implement flash ROM support. Files of this type are w49f002u.c, w39v040fa.c, etc. • Flash_chip_part_number.h. This is not a file name but a placeholder for the files that declare flash ROM support. Files of this type are w49f002u.h, w39v040fa.h, etc. Consider the execution flow of the main application.

We will also discuss a few algorithm design choices to make ‘seem impossible’ cases become possible. #### Iterative Complete Search: UV 725 - Division **Problem statement:** Find and display all pairs of 5-digit numbers that, between them, use the digits 0 through 9 exactly once, such that the first number divided by the second is equal to an integer, i.e., for \( x \) and \( y \) the subject \( \frac{x}{y} = n \), where each letter represents a different digit. The first digit of one of the numbers is allowed to be zero, e.g., for \( n = 2 \), we have \( 79696 / 02368 = 2 \). A quick analysis shows that \( x \) and \( y \) can only range from 01234 to 98765, which is over 100K possibilities. For each result \( n \), we can get above from \( n + 1 \) and think of all digits are different, 100K equations are small. Thus, Iterative Complete Search is feasible. **Exercise 3.2.1.1:** What is the advantage of iterating through \( x \) and \( y \) instead of brute force? **Exercise 3.2.1.2:** Checking directly from 01234 to 98765 is wasteful. There is a smaller and superior approach than 98765. What is the better upper bound value? **Exercise 3.2.1.3:** Solve UV 471 - Magic Numbers which is very similar to this complete search. #### Recursive Backtracking: UV 750 - 8 Queens Chess Problem **Problem statement:** In this problem (a standard \( 8 \times 8 \) board), it is possible to place eight queens on the board such that no two queens attack each other. This means that will eliminate all possible arrangements where the queens can influence each other’s positions (i.e., cannot be in the same row, column, or diagonal). Display the position in lexicographical order. The recursive backtracking algorithm to solve this problem works as follows: To find placed queens in an \( 8 \times 8 \) board, begin with possible positions. - Let \( Q(i, j) \) be the position of a queen at \((i, j)\). - Place a queen in a, e.g., \((1, 1)\) and check valid placements for the next queen that do not violate the rule, updating the configuration until a position is found that fulfills the criteria. We provide code in the next page. If you have pasted a recursive backtracking solution before, please scrutinize it and reproduce it using your own coding style. ![Figure 3.1: 8-Queens Problem](path/to/image) % Insert the relevant image path here ``` #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 716 Context: collectiveoutlierdetection,548,582categoriesof,576contextualoutlierdetectionversus,575ongraphdata,576structurediscovery,575collectiveoutliers,575,581mining,575–576co-locationpatterns,319,595colossalpatterns,302,320coredescendants,305,306corepatterns,304–305illustrated,303miningchallenge,302–303Pattern-Fusionmining,302–307combinedsignificance,312complete-linkagealgorithm,462completenessdata,84–85dataminingalgorithm,22complexdatatypes,166biologicalsequencedata,586,590–591graphpatterns,591–592mining,585–598,625networks,591–592inscienceapplications,612 #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 716 Context: collectiveoutlierdetection,548,582categoriesof,576contextualoutlierdetectionversus,575ongraphdata,576structurediscovery,575collectiveoutliers,575,581mining,575–576co-locationpatterns,319,595colossalpatterns,302,320coredescendants,305,306corepatterns,304–305illustrated,303miningchallenge,302–303Pattern-Fusionmining,302–307combinedsignificance,312complete-linkagealgorithm,462completenessdata,84–85dataminingalgorithm,22complexdatatypes,166biologicalsequencedata,586,590–591graphpatterns,591–592mining,585–598,625networks,591–592inscienceapplications,612 #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 86 Context: # 3.6 Chapter Notes **Steven & Feltis** Many problems in ICPC or IC require one or combinations (see Section 3.2) of these problem-solving paradigms. In here, we have to nominate a chapter in this book that contestants have to really master, and we will discuss this more. The main source of the "Complete Search" material in this chapter is the USACO training gateway [2]. We adopt the term "Complete Search" rather than "Brute Force" as we believe that some "Complete Search" solutions can be cleaner and more refined, although it is complete. We refer to the term "Complete Search" as a self-referential term. We will discuss more advanced search techniques later in Section 3.8, A* Search, Depth Limited Search (DLS), Iterative Deepening (ID), and Iterative Deepening A* (IDA*). Divided and Conquer paradigms is usually stated in the form of its popular algorithm: binary search and its variants, merge/sort (face sort), and data structures: binary tree, heap, segment tree, etc. We will see more about this later in Computational Geometry (Section 7.4). Also, Greedy and Dynamic Programming (DP) techniques/executions are always included in popular algorithm textbooks, see Introduction to Algorithms [3], Algorithm Design [2], Algorithm [4]. However, to keep pace with the growing difficulties and clarity of these techniques, especially the DP techniques, we include more references from Introductory Textbooks and general programming contests in this book. We will revisit DP again for one occasion: First WishList’s DP algorithm (Section 6.7), PA (implied) DAG (Section 3.17), DP-String (Section 6.5), and more Advanced DPs (Section 5.4). However, for some real-life problems, especially those that are classified as NP-Complete [3], many of the approaches discussed so far will not work. For example, a Knapsack Problem with base O(N^5) complexity to know if sub bg P’s BG meets O(N^2 * K) complexity for b too slow if V is much larger than K. For such problems, people use heuristics or local search. Tabu Search [14], 4-Sourcer Algorithm, Ants Colony Optimization, Beam Search, etc. These are 19 UVA (4 + 15 other) programming exercises discussed in this chapter. (Only 10 in the first edition, a 75% increase.) There are 32 pages in this chapter. (Also 32 in the first edition, but some have been restructured to Chapter 4 and 8.) #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 136 Context: # 48.

TCG Architecture Overview Document ![Figure 1.3 Steps in comprehending TCG standards implementation in PC architecture](path/to/image) Figure 1.3 shows that the first document you have to read is the TCG Specification Architecture Overview. Then, proceed to the platform-specific design guide document, which in the current context is the PC platform specification document. You have to consult the concepts explained in the TCG main specification, parts 1–4, and the TSS document while reading the PC platform specification document—the dashed blue arrows in Figure 1.3 mean "consult." You can download the [TCG Specification Architecture Overview](https://www.trustedcomputinggroup.org/specs/TPM). The TSS document is available for download at [TSS Document](https://www.trustedcomputinggroup.org/specs/TSS), and the PC platform specification document is available for download at [PC Client Specification](https://www.trustedcomputinggroup.org/specs/PCCient). The PC platform specification document consists of several files; the relevant ones are the TCG PC Client–Specific Implementation Specification for Conventional BIOS (as of the writing of this book, the latest version of this document is 1.20 final) and the PC Client TPM Interface Specification FAQ. Reading these documents will give you a glimpse of the concepts of trusted computing and some details about its implementation in PC architecture. From here forward, I'll explain a bit more about the fundamental concept of trusted computing that is covered by the TCG standards. The TCG Specification Architecture Overview defines **trust** as the "expectation that a device will behave in a particular manner for a specific purpose." The advanced features that exist in a trusted platform are protected capabilities, integrity measurement, and integrity reporting. The focus is on the integrity measurement feature because this feature relates directly to the BIOS. As per the TCG Specification Architecture Overview, integrity measurement is "the process of obtaining metrics of platform characteristics that affect the integrity (trustworthiness) of a platform; storing those metrics; and putting digests of those metrics in PCRs [platform configuration registers]."

The experiment demonstrates the effectiveness of semantic pattern annotation to generate a dictionary-like annotation for frequent patterns, which can help a user understand the meaning of annotated patterns. The context modeling and semantic analysis method presented here is general and can deal with any type of frequent patterns with context information. Such semantic annotations can have many other applications such as ranking patterns, categorizing and clustering patterns with semantics, and summarizing databases. Applications of the pattern context model and semantically enhanced method are also not limited to pattern annotation; other example applications include pattern compression, transaction clustering, pattern relations discovery, and pattern synonym discovery. ## 7.6.2 Applications of Pattern Mining We have studied many aspects of frequent pattern mining, with topics ranging from efficient mining algorithms and the diversity of patterns to pattern interestingness, pattern #################### File: BIOS%20Disassembly%20Ninjutsu%20Uncovered%201st%20Edition%20-%20Darmawan%20Salihun%20%28PDF%29%20BIOS_Disassembly_Ninjutsu_Uncovered.pdf Page: 363 Context: Before I show you the content of these new files, I explain the changes that I made to accommodate this new feature in the other source code files.
