Solution: Reverse String

Understand how to reverse a string represented as a character array by swapping characters using two pointers. Learn to implement an in-place solution that modifies the original array efficiently without extra memory, ensuring optimal time and space complexity.

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) ...
