Task 4: Write a program which asks users to enter a 3-digit non-negative integer n and print the reverses digits of n. For example, if n2456, the program will print "Reverse of 456 is 654 . ". reverseNumber () is a function which takes a 3-digit non-negative integer n as parameter and reverses the digits of 11. To reverse n, the function uses another function threeDigitSeparator () which separates each digit of n and return those digits. Once threeDigitSeparatorU has separated all digits, reverseNumber () calls another function threeDigitJoiner (J which joins first, second, and third digit in a manner that the final result is reverse of n and returns this joined value.
