In cryptography, you could often break the algorithm if you know what was the original (plain) text that was encoded into the current ciphertext. This is called the plain text attack. In this simple problem, we illustrate the plain text attack on a simple substitution cipher encryption, where you know each letter has been substituted with a different letter from the alphabet but you don’t know what that letter is. You are given the cipherText as the input string to the function getwordSets(). You know that a plain text "AMMUNITION" occurs somewhere in this cipher text. Now, you have to find out which sets of characters corresponds to the encrypted form of the "AMMUNITION". You can assume that the encryption follows simple substitution only. [Hint: You could use the pattern in the "AMMUNITION" like MM occurring twice together to identify this]

The purpose of this exercise is to benchmark file writing and reading speed. This exercise is divided into two parts. a). Write a file character by character such that the total file size becomes approximately >10K. After writing close the file handler, open a new stream and read the file character by character. Record both times. Execute this exercise at least 4 times b). Create a buffer capable of storing 100 characters. Now after generating the characters, first store them in the buffer. Once the buffer is filled up, store all the elements in the file. Repeat the process until the total file size becomes approximately >10K.While reading read a while line, store it in buffer and once buffer gets filled up, display the whole buffer. Repeat the exercise at least 4 times with different size of buffer (50, 100, 150 …). Records the times. c). Do an analysis of the differences in times and submit it in class.
