Alice and Bob, two students of CS 331, were asked to provide algorithms for a simple program.The program is supposed to receive a stream of integers as input. After each input integer, the program must report the average of the integers it has seen so far. Alice and Bob came up with the following algorithms to do this simple task, as in Algorithm 1 and 2, respectively.State whether Alice and Bob have provided correct algorithms, ignoring truncation due to integer division. Also, either prove the algorithm to be right, or show how it is wrong. If there are any incorrect steps in the algorithms, suggest rectifications to correct the mistake.___________________________________________________________________________________________________________________Algorithm 1: Alice's AlgorithmInitially sum is 0 and count of integers read is 0; while the input stream is not empty doRead the integer i;add i to the sum;report average as sum/count;increase count by 1;____________________________________________________________

Trojan HorsesRevisit the permissions on the /shared_data/accounting.txt file. Bob is unable to read this file, but he would very much like to know its content.Bob knows Alice is a fool for ASCII art, and so he creates the /shared data/bob/fun script. View and take a screenshot of this file's contents with an appropriate command (as Bob). Your output should look fun/maybe be some ASCII art.As Bob, can you modify that script so that if Alice (or Harry) run the script, it will make a copy of the accounting.txt file in a manner that allows Bob to see the content? In other words, when Alice runs the file, Bob gets access to the filePlay around with the permissions and see how far you can get, as Bob, in gaining access to Alice's accounting.txt file. You might want to check the permissions on the /shared_data directory check out the ls command options for the appropriate flag to do this.

three different materials, designated a, b, and c, are tested in tension using test specimens hav- ing diameters of 0.505 in. and gage lengths of 2.0 in. (see figure). at failure, the distances between the gage marks are found to be 2.13, 2.48, and 2.78 in., respec- tively. also, at the failure cross sections, the diameters are found to be 0.484, 0.398, and 0.253 in., respectively. determine the percent elongation and percent reduction in area of each specimen. using your own judgment, classify each material as brittle or ductile.
