For a string sequence, a string wordis k-repeating if wordconcatenated ktimes is a substring of sequence. The word's maximum k-repeating value is the highest value kwhere wordis k-repeating in sequence. If wordis not a substring of sequence, word's maximum k-repeating value is 0.

Given strings sequenceand word, return the maximum k-repeating value of wordin 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

sequenceand wordcontains only lowercase English letters.
