Question
Rewrite the program below using a looping statement. You may use either a while loop, do loop, or for loop. Please include a brief statement in a comment in your program stating the assumptions you made to pick your looping statement. That is, if the loop is deterministic or inderministic and if the loop is entrance-controlled or exit-controlled.
