1668 - Maximum Repeating Substring\.
Easy
For a string `sequence`, a string `word` is **`k`\-repeating** if `word` concatenated `k` times is a substring of `sequence`. The `word`'s **maximum `k`\-repeating value** is the highest value `k` where `word` is `k`\-repeating in `sequence`. If `word` is not a substring of `sequence`, `word`'s maximum `k`\-repeating value is `0`.
Given strings `sequence` and `word`, return _the **maximum `k`\-repeating value** of `word` in `sequence`_.
**Example 1:**
**Input:** sequence = "ababc", word = "ab"
**Output:** 2
**Explanation:** "abab" is a substring in "ababc".
**Example 2:**
**Input:** sequence = "ababc", word = "ba"
**Output:** 1
**Explanation:** "ba" is a substring in "ababc". "baba" is not a substring in "ababc".
**Example 3:**
**Input:** sequence = "ababc", word = "ac"
**Output:** 0
**Explanation:** "ac" is not a substring in "ababc".
**Constraints:**
* `1 <= sequence.length <= 100`
* `1 <= word.length <= 100`
* `sequence` and `word` contains only lowercase English letters.
