Longest Substring of One Repeating Character

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 i^th 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 i^th query is performed.

Example 1
Inputs = "babacc", queryCharacters = "bcb", queryIndices = [1,3,3]
Output[3,3,4]
After the three updates, the longest one-character repeating substrings have lengths 3, 3, and 4, respectively.
Example 2
Inputs = "abyzz", queryCharacters = "aa", queryIndices = [2,1]
Output[2,3]
After the two updates, the longest one-character repeating substrings have lengths 2 and 3, respectively.

Constraints

  • 1 <= s.length <= 10^5
  • s consists of lowercase English letters.
  • k == queryCharacters.length == queryIndices.length
  • 1 <= k <= 10^5
  • queryCharacters consists of lowercase English letters.
  • 0 <= queryIndices[i] < s.length
