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.
