Medium
30 min
Explore the sliding window technique to determine the longest substring in a string where all characters can be made identical by replacing at most k characters. This lesson guides you through understanding the problem, developing a solution approach, and implementing the algorithm efficiently with practical coding exercises.
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:
s.lengthsconsists of only uppercase English characters.ks.length
