Second Time I have submitted this. The first time was an incorrect answer. I don't know what I did wrong with "Test digitCount(0) and how to fix it.
Transcribed Image Text:Write a recursive function called DigitCount() that takes a non-negative integer as a parameter and returns the number of digits in the
integer. Hint: The digit count increases by 1 whenever the input number is divided by 10.
Ex: If the input is:
345
the function DigitCount() returns and the program outputs:
