 // d) What is the value assigned to num when pad is called for the last time in this program?  Explain your answer

+// =============> 1. The last pad call takes `remainingSeconds` as its argument, and 61 % 60 =1 , so num is 1.
 // e) What is the return value of pad when it is called for the last time in this program?  Explain your answer
-// =============> write your answer here
+// =============> 01. `numString` starts as "1", which has one character length. Since 1 < 1, the while lines run and pad "0", giving "01". Now this new `numString` has two characters length, so the while loop stops and returns "01".
