Write a loop that asks the user "do you want to repeat the program or quit? (r/q) ". the loop should repeat until the user has entered an r or q (either uppercase or lowercase).

Here is the loop:for (int i = 0; i < S. length (); i++) S. charAt (i) = = 'q'); System. out. println (""do you want to repeat the program or quit? (r/q) "");

If the user enter any of the characters in the if statement the user will be asked by the question.
