A niven number is a non-negative number that is divisible by the sum of its digits.
Write a function/method named niven which prints all the niven numbers from 0 to 100 inclusive, each on their own line. The function needs to compute the solution, i.e., it is not acceptable to use any pre-computed data structure or solution.
