Use recursion to determine the number of digits in an integer n.

Hint: If n is < 10, it has one digit. Otherwise, it has one more digit than n / 10.

Write the method and then write a test program to test the method

Your test program must:

Ask the user for a number

Print the number of digits in that number. (describe the numbers printed to the console)

Use comments to describe your base case and recursive case in detail (as we did in the lecture)

Use program headers and method header comments in your code.
