Solution: Longest Repeating Character Replacement
Explore the sliding window technique to solve the problem of finding the longest substring where up to k characters can be replaced to form a uniform substring. Understand how to use two pointers, frequency tracking, and window adjustments to optimize the solution with O(n) time complexity and constant space.
Statement
