 // a) When formatTimeDisplay is called how many times will pad be called?
 // =============> write your answer here
 
+//formatTimeDisplay will call pad three times, once for totalHours, once for

 // 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
+// The value assigned to num when pad is called for the first time is 0, which is the value 
+// of totalHours when the input is 61 seconds.
 
 // c) What is the return value of pad when it is called for the first time?
 // =============> write your answer here
 
+// The return value of pad when it is called for the first time is "00", which is the string
+//  representation of totalHours padded with a leading zero.
+
 // 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 to num when pad is called for the last time in this program is 1, 
+// which is the value of remainingSeconds when the input is 61 seconds. This is because 61 
+// seconds has 1 second remaining after calculating the total minutes and hours.
 
 // 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 of pad when it is called for the last time in this program is "01", 
+// which is the string representation of remainingSeconds padded with a leading zero. 
+// This is because the value of remainingSeconds is 1, and the pad function adds a leading 
+// zero to make it a two-digit string.
