Explore how to reverse a character array in-place by applying the two pointers technique. This lesson guides you to implement an efficient solution that modifies the original string directly without extra memory, reinforcing skills essential 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) ...
