    2213 - Longest Substring of One Repeating Character.

    Hard

    You are given a 0-indexed string s. You are also given a 0-indexed string queryCharacters of length k and a 0-indexed array of integer indices queryIndices of length k, both of which are used to describe k queries.

    The ith query updates the character in s at index queryIndices[i] to the character queryCharacters[i].

    Return an array lengths of length k where lengths[i] is the length of the longest substring of s consisting of only one repeating character after the ith query is performed.

    Example 1:

    Input: s = “babacc”, queryCharacters = “bcb”, queryIndices = [1,3,3]

    Output: [3,3,4]

    Explanation: - 1st query updates s = “bbbacc”. The longest substring consisting of one repeating character is “bbb” with length 3.

    • 2nd query updates s = “bbbccc”. The longest substring consisting of one repeating character can be “bbb” or “ccc” with length 3.

    • 3rd query updates s = “bbbbcc”. The longest substring consisting of one repeating character is “bbbb” with length 4.

    Thus, we return [3,3,4].

    Example 2:

    Input: s = “abyzz”, queryCharacters = “aa”, queryIndices = [2,1]

    Output: [2,3]

    Explanation: - 1st query updates s = “abazz”. The longest substring consisting of one repeating character is “zz” with length 2.

    • 2nd query updates s = “aaazz”. The longest substring consisting of one repeating character is “aaa” with length 3.

    Thus, we return [2,3].

    Constraints:

    • 1 <= s.length <= 105
    • s consists of lowercase English letters.
    • k == queryCharacters.length == queryIndices.length
    • 1 <= k <= 105
    • queryCharacters consists of lowercase English letters.
    • 0 <= queryIndices[i] < s.length
