Solution: Reverse String

Understand how to reverse a character array in place by applying the two pointers technique. This lesson demonstrates swapping characters from each end of the array to reverse it efficiently without extra space, focusing on optimizing time and space complexity in string manipulation.

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) ...
