# [Solution] Find the K-Beauty of a Number solution leetcode

Find the K-Beauty of a Number solution leetcode – The k-beauty of an integer `num` is defined as the number of substrings of `num` when it is read as a string that meet the following conditions:

## [Solution] Find the K-Beauty of a Number solution leetcode

• It has a length of `k`.
• It is a divisor of `num`.

Given integers `num` and `k`, return the k-beauty of `num`.

Note:

• `0` is not a divisor of any value.

substring is a contiguous sequence of characters in a string.

## [Solution] Find the K-Beauty of a Number solution leetcode

```Input: num = 240, k = 2
Output: 2
Explanation: The following are the substrings of num of length k:
- "24" from "240": 24 is a divisor of 240.
- "40" from "240": 40 is a divisor of 240.
Therefore, the k-beauty is 2.
```

## [Solution] Find the K-Beauty of a Number solution leetcode

```Input: num = 430043, k = 2
Output: 2
Explanation: The following are the substrings of num of length k:
- "43" from "430043": 43 is a divisor of 430043.
- "30" from "430043": 30 is not a divisor of 430043.
- "00" from "430043": 0 is not a divisor of 430043.
- "04" from "430043": 4 is not a divisor of 430043.
- "43" from "430043": 43 is a divisor of 430043.
Therefore, the k-beauty is 2.
```

Constraints:

• `1 <= num <= 109`
• `1 <= k <= num.length` (taking `num` as a string)
