Solution: Number of Substrings Containing All Three Characters
Understand how to use the sliding window pattern to efficiently count substrings containing all three characters 'a', 'b', and 'c'. Learn to implement a two-pointer approach that expands and shrinks a window while tracking character counts, optimizing both time and space complexity. This lesson equips you with a practical technique to solve substring counting problems commonly asked in coding interviews.
