 // 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 seconds is 61.
 
 // c) What is the return value of pad 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". Since num is 0, the while loop adds a "0" to the front of numString until its length is 2, resulting in "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 to num when pad is called for the last time in this program is 1, which is the value of remainingSeconds when seconds is 61. This is because 61 seconds is equal to 1 minute and 1 second, so remainingSeconds is calculated as 61 % 60, which equals 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 of pad when it is called for the last time in this program is "01". Since num is 1, the while loop adds a "0" to the front of numString until its length is 2, resulting in "01".
