Solution: Longest Repeating Character Replacement
Explore the sliding window approach to solve the longest repeating character replacement problem in a string. Learn how to maintain and adjust a dynamic window using two pointers and a frequency map to track character occurrences, ensuring the substring can be transformed into one with identical characters by replacing at most k characters. Understand the implementation, time complexity, and space complexity of this linear-time solution.
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.
