18.8 (Print the digits in an integer reversely)
Write a recursive method that displays an int value reversely
on the console using the following header:
public static void reverseDisplay(int value)
For example, reverseDisplay(12345) displays 54321. Write a test program
that prompts the user to enter an integer and displays its reversal.
