Solution: Reverse String

Explore how to reverse a character array in-place by applying the two pointers technique. Understand the step-by-step process of swapping characters from both ends towards the center without extra memory. This lesson helps you implement an efficient solution with linear time and constant space complexity, improving your problem-solving skills for coding interviews.

Statement

You are given a character array, s, representing a string. Write a function that reverses the array in-place.

  • The reversal must be done by modifying the original array directly.

  • You cannot use extra memory beyond a constant amount O(1)O(1) ...
