2325// a) When formatTimeDisplay is called how many times will pad be called?
24- // =============> write your answer here
26+ // The function pad will be called three times
2527
2628// Call formatTimeDisplay with an input of 61, now answer the following:
2729
2830// b) What is the value assigned to num when pad is called for the first time?
29- // =============> write your answer here
31+ // num is assigned value of totalHours when pad is called first time because js evaluates expressions from left to right

32- // =============> write your answer here
34+ // The return value will be "00"

3436// d) What is the value assigned to num when pad is called for the last time in this program? Explain your answer
35- // =============> write your answer here
37+ // num will be assigned the value of remainingSeconds when pad is called for the last time because js evaluates any expression
38+ // from left to right and the pad with argument remainingSeconds is found at the right end

3740// e) What is the return value of pad when it is called for the last time in this program? Explain your answer
38- // =============> write your answer here
41+ // The return value of pad when it is called for the last time is "01"
42+ // We calculated remainingSeconds in the function formatTimeDisplay and we got the value 1 then when pad is called with
43+ // an argument value of remainingSeconds we changed the value to string and 0 is added before 1 and it became 2 digits which is "01"
