It is used when an important number of choices are to be considered depending on the value of a variable. Repetition structures define the order of operations and the number of repetitions.
They are also known as loops. Examples are, while…do, repeat…until, for…to…do. When the condition becomes false, the loop stops. The condition for the loop to stop comprises of a variable called control or iteration variable whose value must change at the end of each execution of the loop. Get n Action 1 b. If it evaluates to false, the instruction or set of instructions is executed again. If condition evaluates to true, the program exits the loop. The Repeat until loop must be executed at least once as the condition is evaluated only at the end of the loop.

Some books on algorithms are rigorous but incomplete; others cover masses of material but lack rigor. Introduction to Algorithms uniquely combines rigor and comprehensiveness.
The book covers a broad range of algorithms in depth, yet makes their design and analysis accessible to all levels of readers. Each chapter is relatively self-contained and can be used as a unit of study. The algorithms are described in English and in a pseudocode designed to be readable by anyone who has done a little programming. Since we emphasize efficiency as a design criterion, we include careful analyses of the running times of all our algorithms.
The text is intended primarily for use in undergraduate or graduate courses in algorithms or data structures. Because it discusses engineering issues in algorithm design, as well as mathematical aspects, it is equally well suited for self-study by technical professionals.
In this, the second edition, we have updated the entire book. I will definitely recommend this book to science, computer science lovers. Your Rating:. Your Comment:. Cormen Submitted by: Jane Kivik. Read Online Download.
