 // Questions
 
 // a) When formatTimeDisplay is called how many times will pad be called?
-// =============> write your answer here
+// =============> pad will be called 3 times, once for pad(totalHours, 
+// once for (pad)remainingMinutes and once for (pad)remainingSeconds
+
 
 // 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 first call to pad is pad(totalHours).
+//totalHours is calculated as totalMinutes // 60.
+//For the input 61, seconds is 61, remainingSeconds is 1, and totalMinutes is 1.
+//So, totalHours is 1 // 60 = 0.
+//Therefore, num is assigned the value 0 when pad is called for the first time.
+
 
 // c) What is the return value of pad is called for the first time?
-// =============> write your answer here
+// =============> The first call to pad is pad(totalHours).
+//totalHours is calculated as totalMinutes // 60.
+//For the input 61, totalMinutes is (61 - 1) // 60 = 1.
+//So, totalHours is 1 // 60 = 0.
+//pad(0) returns the string representation of 0, padded with zeros to a minimum length of 2, which is "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
+// =============> We look at the last call to pad, which is pad(remaining_seconds).
+//remaining_seconds is calculated as seconds % 60.
+//For the input 61, seconds % 60 equals 1.
+//So, pad(remaining_seconds) is equivalent to pad(1). The value assigned to num in the last call to pad is 1.
+
 
 // e) What is the return value assigned to num when pad is called for the last time in this program?  Explain your answer
-// =============> write your answer here
+// =============> For the input 61, remaining_seconds will be 1. So, pad(1) will return "01". Therefore, the value assigned to num is 1.
