Solution: Longest Repeating Character Replacement

Explore the sliding window technique to efficiently solve the longest repeating character replacement problem. This lesson helps you implement a method to track character frequencies and adjust substring windows dynamically to find the maximum length substring after at most k character replacements, optimizing time complexity to O(n).

Statement

Given a string, s, and an integer, k, find the length of the longest substring in s, where all characters are identical, after replacing, at most, k characters with any other uppercase English character.
