Question 10

Code the following in Java using Recursion

/**
* TODO: Using only recursion, implement is DivisibleBy without '%' or '/'
*
* Given two integers input and base, you are to return (without use of modulus '%'
* or division '/' operators):
*
*
*
* You are NOT allowed to use the modulus '%' operator nor the division '/' operator
* in this problem, nor anything from the Math library.
*
* BIG HINT: You will probably want to use subtraction...
*
* Examples:
* 1) isDivisibleBy (21, 7) -> return true
* 2) isDivisibleBy (21, 6) -> return false
* 3) isDivisible By (9, 9) -> return true
isDivisibleBy (64, 8) -> return true
* 4)
* 5) isDivisibleBy (48, 5) -> return false
*
true: if input is divisible by base (remainder of 0)
false: if input is not divisible by base (remainder of anything else)
* @param input
* @param base
* @return true if input % base 0, otherwise false
