(Convert milliseconds to hours, minutes, and seconds) Write a function that converts milliseconds to hours, minutes, and seconds using the following header: def convertMillis(millis): The function returns a string as hours:minutes:seconds. For example, convertMillis(5500) returns the string 0:0:5, convertMillis(100000) returns the string 0:1:40, and convertMillis(555550000) returns the string 154:19:10. Write a test program that prompts the user to enter a value for milliseconds and displays a s

Answer:I am writing the Python program. Let me know if you want the program in some other programming language.def convertMillis(millis):  #function to convert milliseconds to hrs,mins,secs    remaining = millis  # stores the value of millis to convert    hrs = 3600000  # milliseconds in hour    mins = 60000  # milliseconds in a minute    secs = 1000  #milliseconds in a second    hours =remaining / hrs  #value of millis input by user divided by 360000    remaining %= hrs  #mod of remaining by 3600000    minutes = remaining / mins  # the value of remaining divided by 60000    remaining %= mins  #mod of remaining by 60000    seconds = remaining / secs  #the value left in remaining variable is divided by 1000    remaining %= secs  #mod of remaining by 1000    print ("%d:%d:%d" % (hours, minutes, seconds))#displays hours mins and seconds with colons in between     def main():  #main function to get input from user and call convertMillis() to #convert the input to hours minutes and seconds    millis=input("Enter time in milliseconds ")  #prompts user to enter time    millis = int(millis)  #converts user input value to integer    convertMillis(millis)   #calls function to convert input to hrs mins secsmain() #calls main() function Explanation:The program is well explained in the comments mentioned with each line of code. The program has two functions convertMillis(millis) which converts an input value in milliseconds to hours, minutes and seconds using the formula given in the program, and main() function that takes input value from user and calls convertMillis(millis) for the conversion of that input. The program along with its output is attached in screenshot.
