Given an integer num, return the number of digits in num that divide num.

\n\n

An integer val divides nums if nums % val == 0.

\n\n

 

\n

Example 1:

\n\n
\nInput: num = 7\nOutput: 1\nExplanation: 7 divides itself, hence the answer is 1.\n
\n\n

Example 2:

\n\n
\nInput: num = 121\nOutput: 2\nExplanation: 121 is divisible by 1, but not 2. Since 1 occurs twice as a digit, we return 2.\n
\n\n

Example 3:

\n\n
\nInput: num = 1248\nOutput: 4\nExplanation: 1248 is divisible by all of its digits, hence the answer is 4.\n
