String Manipulation Message = "HelloWorld" Assume you have a random string of length 15 Insert the string at beginning of the Message In other words, create a string x = x1x2...Xn+15 such that x1 ...X15 is the random string we generated and X16 ...Xn+15 is our original message. Lastly construct string y using x: yi = {- xi (xi + Yi-15) mod 26) for 1 si s 15 for 14
