Solution: Reverse String

Explore the two pointers method to reverse a string in place efficiently. This lesson teaches you how to swap characters from both ends of an array until the middle, achieving reversal with constant space and linear time complexity. You will understand how to modify the original string without extra memory and grasp the algorithm's step-by-step process in practical coding scenarios.

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) ...
