It is a well-known phenomenon that most people are easily able to read a text whose words have two characters flipped, provided the first and last letter of each word are not changed. for example, i dn’ot gvie a dman for a man taht can olny sepll a wrod one way. (mrak taiwn) write a method string scramble(string word) that constructs a scrambled version of a given word, randomly flipping two characters other than the first and last one. then write a program that reads words and prints the scrambled words .
