Solution: String Compression
Explore how to apply two pointers to perform in-place string compression by identifying consecutive character groups and encoding their counts. This lesson teaches an efficient run-length encoding approach that optimizes space usage while modifying the input array directly. You will understand how to handle groups of different lengths and implement the solution with O(n) time and O(1) space complexity.
