+The value assigned to num when pad is called for the last time is 1.
+The last call to pad in the template literal is pad(remainingSeconds). Since remainingSeconds = 61 % 60 = 1, the value passed to num is 1. This will return "01" after padding, resulting in the final output "00:01:01"

 // e) What is the return value assigned to num when pad is called for the last time in this program?  Explain your answer

+/*
+The return value of the last call to pad is "01".
+Explanation: When pad is called with remainingSeconds (which equals 1), the parameter num receives the value 1. The function then converts it to a string "1", 
+pads it to 2 characters with leading zeros to get "01", and returns this string. This returned value "01" 
+is then inserted into the template literal as the last part of the time display, producing the final output "00:01:01".

+Test Groups Created:
+1. Midnight (00:xx) - Edge case for start of day
+2. Morning hours (01-11) - Standard AM times
+3. Noon (12:xx) - Edge case for 12 PM
+4. Afternoon/Evening (13-23) - Standard PM times requiring conversion
+5. Minutes preservation - Ensures minutes aren't lost
+
+Bugs Found:
+1. Midnight bug: "00:00" returns "00:00 am" instead of "12:00 am"
+2. Noon bug: "12:00" returns "12:00 am" instead of "12:00 pm"
+3. Minutes lost: All times lose their minutes and show :00 (e.g., "13:13" becomes "1:00 pm" instead of "1:13 pm")
+4. Leading zeros: Morning times keep the input format including leading zeros
