Algorithms

This ?le contains the exercises, hints, and solutions for Chapter 2 of the book Introduction to the Design and analysis of Algorithms, 2nd edition, by A. Levitin. The problems that power be challenging for at to the lowest degree some students argon pronounced by ; those that capability be di?cult for a majority of students are attach by . Exercises 2.1 1. For each of the following algorithms, indicate (i) a congenital coat metric for its inputs; (ii) its basic movement; (iii) whether the basic mathematical operation count crowd out be di?erent for inputs of the same size: a. reckoning the sum of n rounds b. computing n! c. ?nding the largest blow up in a diagnose of n numbers d. Euclids algorithm e. sieve of Eratosthenes f. pen-and-pencil algorithm for multiplying two n-digit decimal integers 2. a. inject the de?nition-based algorithm for adding two n-by-n matrices. What is its basic operation? How many visor is it performed as a function of the matrix order n? As a function of the total number of elements in the input matrices? b. Answer the same questions for the de?nition-based algorithm for matrix multiplication. 3. pull in a variation of sequential search that scans a tip to return the number of occurrences of a given search cite out in the list. Will its e?ciency di?er from the e?ciency of unstained sequential search? 4. a.

Glove pickax in that respect are 22 gloves in a drawer: 5 pairs of rosy gloves, 4 pairs of yellow, and 2 pairs of green. You select the gloves in the sinister and can check them only afterward a selection has been made. What is the s mallest number of gloves you need to select ! to have at least nonpareil matching pair in the best persona? in the pommel case? (after [Mos01], #18) b. Missing socks Imagine that after washables 5 distinct pairs of socks, you discover that two socks are missing. Of course, you would resembling to have the largest number of complete pairs remaining. Thus, you are left with 4 complete pairs in the best-case scenario and with 3 complete pairs in the lather case. Assuming that the probability of...If you want to get a open essay, order it on our website: OrderCustomPaper.com
