Find Digits code in C#

You are given an integer N. Find the digits in this number that exactly divide N (division that leaves 0 as remainder) and display their count. For N=24, there are 2 digits (2 & 4). Both of these digits exactly divide 24. So our answer is 2.

Note

  • If the same number is repeated twice at different positions, it should be counted twice, e.g., For N=122, 2 divides 122 exactly and occurs at ones’ and tens’ position. So for this case, our answer is 3.
  • Division by 0 is undefined.

Input Format

The first line contains T (the number of test cases), followed by T lines (each containing an integer N).

Constraints
1T15
0<N<1010

Output Format

For each test case, display the count of digits in N that exactly divide N in a separate line.

Sample Input

2
12
1012

Sample Output

2
3

Explanation

2 digits in the number 12 divide it exactly. The first digit, 1, divides it exactly in twelve parts, and the second digit, 2 divides 12 equally in six parts.

1 divides 1012 exactly (and it occurs twice), and 2 also divides it exactly. Division by 0 is undefined, therefore it will not be counted.

{
static void Main(string[] args)
{
int T = Convert.ToInt16(Console.ReadLine());
int count = 0;
for (int i = 0; i < T; ++i)
{
count = 0;
string N = Console.ReadLine();
foreach (char ch in N)
{
if ((ch != ‘0’) && (Convert.ToInt64(N) % Convert.ToInt16(ch – ‘0’) == 0))
{
++count;
}
}
Console.WriteLine(count);
}
}
}
