Remember that it is desirable for good block ciphers that a change in one input bit affects many output bits, a property that is called diffusion or the avalanche effect. We try now to get a feeling for the avalanche property of DES. We apply an input word that has a "1" at bit position 33 and all other bits as well as the key are zero. (Note that the input word has to run through the initial permutation.) 1. How many S-boxes get different inputs compared to the case when an all-zero plaintext is provided? 2. What is the minimum number of output bits of the S-boxes that will change according to the S-box design criteria? 3. What is the output after the ļ¬rst round? 4. How many output bit after the ļ¬rst round have actually changed compared to the case when the plaintext is all zero? (Observe that we only consider a single round here. There will be more and more output differences after every new round. Hence the term avalanche effect.)

Simon says is a memory game where "simon" outputs a sequence of 10 characters (r, g, b, y) and the user must repeat the sequence. create a for loop that compares the two strings starting from index 0. for each match, add one point to userscore. upon a mismatch, exit the loop using a break statement. assume simonpattern and userpattern are always the same length. ex: the following patterns yield a userscore of 4: simonpattern: rrgbryybgy userpattern: rrgbbrybgy

Write a defining table and then a program that determines if you can sleep in or not. your program should get all its input from your computerās clock. on all weekdays (monday through friday) that are not holidays, your program should output āget up! ā on all other days (weekends and holidays), your program should output āsleep in.ā the three holidays that your program must check for are january 1 (new yearās day), july 4 (u. s. independence day), and december 25 (christmas). you donāt need to include other holidays in your program because most other holidays do not occur on a fixed day each year.
