 // Questions
 
 // a) When formatTimeDisplay is called how many times will pad be called?
-// =============> write your answer here
+// 3 times (once for hours, once for minutes and once for seconds)
 
 // Call formatTimeDisplay with an input of 61, now answer the following:
 
 // b) What is the value assigned to num when pad is called for the first time?
-// =============> write your answer here
+// With an input of 61 seconds, totalHours evaluates to 0. Therefore, num is assigned  0 on the first call
 
 // c) What is the return value of pad when it is called for the first time?
-// =============> write your answer here
+// The return value is "00". Since the input is 0, its string length is less than 2, so the while loop runs it twice to prepend two zeros ("00")
 
 // d) What is the value assigned to num when pad is called for the last time in this program?  Explain your answer
-// =============> write your answer here
+// The value assigned is 1. This is for remainingSeconds, which receives the remainder of 61 % 60, resulting in 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
+// The return value is "01". Because the input is 1, its string length is less than 2, so the while loop runs once to prepend a single zero("01")
