Understanding the Longest Substring of One Repeating Character Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
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.

How Interview Coder Helps
Get real-time assistance for Longest Substring of One Repeating Character problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
s = "babacc", queryCharacters = "bcb", queryIndices = [1,3,3][3,3,4]- 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].
s = "abyzz", queryCharacters = "aa", queryIndices = [2,1][2,3]- 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].
