Solution: Reverse String

Understand how to reverse a string in-place by swapping characters using the two pointers technique. This lesson guides you through implementing an efficient solution with constant space and linear time complexity, enhancing your algorithm 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) ...
