**Find Digits**

### Problem Statement :

An integer d is a divisor of an integer n if the remainder of n/d = 0. Given an integer, for each digit that makes up the integer determine whether it is a divisor. Count the number of divisors occurring within the integer. Example n = 124 Check whether 1, 2 and 4 are divisors of 124. All 3 numbers divide evenly into 124 so return 3. n = 111 Check whether 1, 1, 1 and are divisors of 111. All 3 numbers divide evenly into 111 so return 3. n = 10 Check whether 1 and 0 are divisors of 10. 1 is, but 0 is not. Return 1. Function Description Complete the findDigits function in the editor below. findDigits has the following parameter(s): int n: the value to analyze Returns int: the number of digits in n that are divisors of n Input Format The first line is an integer, t, the number of test cases. The t subsequent lines each contain an integer, n. Constraints 1 <= t <= 15 0 < n < 10^9
