It is intended for use in a course on algorithms. That is, for most chapters we have provided a set of lecture notes and a set of exercise and problem solutions pertaining to the chapter.

This organization allows you to decide how to best use the material in the manual in your own course. We have not included lecture notes and solutions for every chapter, nor have we included solutions for every exercise and problem within the chapters that we have selected.

We felt that Chapter 1 is too nontechnical to include here, and Chap-ter 10 consists of background maChap-terial that often falls outside algorithms and data-structures courses. We have also omitted the chapters that are not covered in the courses that we teach: Chapters 18—20 and 28—35, as well as Appendices A—C; future editions of this manual may include some of these chapters.

There are two reasons that we have not included solutions to all exercises and problems in the selected chapters.

First, writing up all these solutions would take a long time, and we felt it more important to release this manual in as timely a fashion as possible. Second, if we were to include all solutions, this manual would be longer than the text itself! We chose this form of page numbering so that if we add or change solutions to exercises and problems, the only pages whose numbering is affected are those for the solutions for that chapter.

Moreover, if we add material for currently uncovered chapters, the numbers of the existing pages will remain unchanged. Some sections of the text—usually starred—are omitted from the lecture notes. We have included lec-ture notes for one starred section: The asides are typeset in a slanted font and are enclosed in square brack-ets.

If you are projecting a presenta-tion rather than writing on a blackboard or whiteboard, you might want to mark slides containing this material so that you can easily come back to them later in the lecture. We have chosen not to indicate how long it takes to cover material, as the time nec-essary to cover a topic depends on the instructor, the students, the class schedule, and other variables. Instead, we pass the array. This change makes the pseudocode more concise, as well as matching better with the description of what it does.

The solutions are based on the same sources as the lecture notes. They are written a bit more formally than the lecture notes, though a bit less formally than the text. We do not number lines of pseudocode, but we do use the length attribute on the assumption that you will want your students to write pseudocode as it appears in the text. The index lists all the exercises and problems for which this manual provides solu-tions, along with the number of the page on which each solution starts.

We apologize for this inconvenience. It enables. That site also includes documentation. Please report errors by sending email toclrs-manual-bugs mhhe.

If you have a suggestion for an improvement to this manual, please feel free to submit it via email toclrs-manual-suggestions mhhe. We thank you in advance for your assistance in correcting errors in both this manual and the text. The other three Introduction to Algorithms authors—Charles Leiserson, Ron Rivest, and Cliff Stein—provided helpful comments and suggestions for solutions to exercises and problems. At this point, we do not know which TAs wrote which solutions, and so we simply thank them collectively.

Phillip Meek of McGraw-Hill helped us hook this manual into their web site. Output: A permutation reordering a 1 ,a 2 ,. We also refer to the numbers as keys. Along with each key may be additional information, known as satellite data. We will see several ways to solve the sorting problem. We express algorithms in whatever way is the clearest and most concise.

English is sometimes the best way. A good algorithm for sorting a small number of elements. It works the way you might sort a hand of playing cards:. An easier option is, when using an array A [1. That saves us a line of pseu-docode each time. The solutions continue to use the length attribute. Insert A [ j ] into the sorted sequence A [1.

Each part shows what happens for a particular itera-tion with the value of j indicated. Elements to the left of A [ j ]that are greater than A [ j ]move one position to the right, and A [ j ]moves into the evacuated position.

The heavy vertical lines separate the part of the array in which an iteration works— A [1. The last part of the. We often use a loop invariant to help us understand why an algorithm gives the correct answer.

Maintenance: If it is true before an iteration of the loop, it remains true before the next iteration. Termination: When the loop terminates, the invariant—usually along with the reason that the loop terminated—gives us a useful property that helps show that the algorithm is correct. The subarray A [1. Rather than getting bogged down in another loop invariant, we instead note that the body of the inner while loop works by moving.

At that point, the value of key is placed into this position. In other words, the entire array is sorted! For an. This would be the equivalent of. If x and y denote objects, then. It does not cause attributes of one object to be copied to another. We want to predict the resources that the algorithm requires. Usually, running time.

In order to predict resource requirements, we need a computational model. Each of these instructions takes a constant amount of time. Like the size n of the array being. Running time: On a particular input, it is the number of primitive operations steps executed. Since the third line. The running time of the algorithm is. They are there for clarity, but it might be a good idea to remind the students that the meaning of the expression would be the same even without the parentheses.

Example: Suppose that we randomly choose n numbers as the input to inser-tion sort. On average, the key in A [ j ] is less than half the elements in A [1. Another abstraction to ease analysis and focus on the important features. Look only at the leading term of the formula for running time. We say that the running time is n 2 to capture the notion that the order of growth. For example, insertion sort is incremental : having sorted A [1. Base case: If the subproblems are small enough, just solve them by brute force.

If they are not, then they will have a hard time understanding divide and conquer. A sorting algorithm based on divide and conquer. Its worst-case running time has a lower order of growth than insertion sort.

Because we are dealing with subproblems, we state each subproblem as sorting a subarray A [ p. Divide by splitting into two subarrays A [ p. Conquer by recursively sorting the two subarrays A [ p. Combine by merging the two sorted subarrays A [ p. The recursion bottoms out on these single-element subproblems. By the. Output: The two subarrays are merged into a single sorted subarray in A [ p.

Cormen Charles E. Leiserson and Ronald L. Rivest — This book provides a comprehensive introduction to the modern study of computer algorithms. It presents many algorithms and covers them in considerable depth, yet makes their design and analysis accessible to all levels of readers.

Cormen, Charles E. Leiserson, Ronald L. Although this covers most of the important aspects of algorithms, the concepts have been detailed in a lucid manner, so as to be palatable to readers at all levels of skill. There is also an area of application or a related topic, so that students can find out the practical implications of the algorithm in question.

Какого черта. Он кивнул. - Si, echame un poco de vodka.

Он бродил по коридорам шифровалки, тушил бесконечные виртуальные пожары и проклинал слабоумие нерадивых невежд. Чатрукьян знал: как только Джабба узнает, что Стратмор обошел фильтры, разразится скандал. Какая разница? - подумал. - Я должен выполнять свои обязанности.

Джабба - дурак! - прошипела. Эти слова его удивили. Никто никогда не называл Джаббу дураком, свиньей - быть может, но дураком - .

*Он быстро подошел к ним и остановился в нескольких сантиметрах от дрожащего Чатрукьяна. - Вы что-то сказали.*
