2520 - Count the Digits That Divide a Number.
Easy
Given an integer num
, return the number of digits in num
that divide num
.
An integer val
divides nums
if nums % val == 0
.
Example 1:
Input: num = 7
Output: 1
Explanation: 7 divides itself, hence the answer is 1.
Example 2:
Input: num = 121
Output: 2
Explanation: 121 is divisible by 1, but not 2. Since 1 occurs twice as a digit, we return 2.
Example 3:
Input: num = 1248
Output: 4
Explanation: 1248 is divisible by all of its digits, hence the answer is 4.
Constraints:
1 <= num <= 109
num
does not contain0
as one of its digits.
