Solution: Longest Repeating Character Replacement

Explore how to solve the longest repeating character replacement problem by applying the sliding window technique. Understand managing character frequencies, window resizing, and optimizing time and space complexity. This lesson guides you through implementing an O(n) solution to identify the longest uniform substring after limited character replacements.

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.

Constraints:

  • 11 \leq s.length 103\leq 10^3

  • s consists of only uppercase English characters.

  • 00 \leq ...
