31- // =============> write your answer here
33+ // value assigned is 1, because pad is called with remainingSeconds as the argument.
34+ // remainingSeconds is the remainder of 61 divided by 60, which is 1.

3336// e) What is the return value of pad when it is called for the last time in this program? Explain your answer
34- // =============> write your answer here
37+ // return value is "01". First, the pad function converts input num to string so the return type is string.
38+ // Second, the function pads the start of the string with up to two "0" characters, and in this case
39+ // since num is a single character, it only pads one "0" at the start.
