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.
\n
Example 1:
\n\n\nInput: s = "babacc", queryCharacters = "bcb", queryIndices = [1,3,3]\nOutput: [3,3,4]\nExplanation: \n- 1st query updates s = "bbbacc". The longest substring consisting of one repeating character is "bbb" with length 3.\n- 2nd query updates s = "bbbccc". \n The longest substring consisting of one repeating character can be "bbb" or "ccc" with length 3.\n- 3rd query updates s = "bbbbcc". The longest substring consisting of one repeating character is "bbbb" with length 4.\nThus, we return [3,3,4].\n\n\n
Example 2:
\n\n\nInput: s = "abyzz", queryCharacters = "aa", queryIndices = [2,1]\nOutput: [2,3]\nExplanation:\n- 1st query updates s = "abazz". The longest substring consisting of one repeating character is "zz" with length 2.\n- 2nd query updates s = "aaazz". The longest substring consisting of one repeating character is "aaa" with length 3.\nThus, we return [2,3].\n\n\n
