Solution: Longest Repeating Character Replacement
Explore the sliding window approach to efficiently solve the longest repeating character replacement problem. Learn to track character frequencies and adjust the window to find the maximum substring length after up to k replacements, improving time efficiency compared to brute force.
Statement
