You are given a file consisting of students names in the following form: lastName, firstName middleName. (Note that a student may not have a middle name.)

Write a program that converts each name to the following form: firstName middleName lastName. Your program must read each students entire name in a variable and must consist of a function that takes as input a string, consists of a students name, and returns the string consisting of the altered name to print to the terminal. Use the string function find to find the index of ,; the function length to find the length of the string; and the function substr to extract the firstName, middleName, and lastName.
