Solution: String Compression
Understand how to apply the two pointers technique for in-place string compression. This lesson teaches you to compress character arrays by encoding consecutive repeating characters, efficiently modifying the input array with constant space. Learn to track groups of characters and write compressed results directly, enhancing your problem-solving skills in coding interviews.
