Solution: Reverse String
Understand how to reverse a character array in-place by using two pointers. This lesson guides you through swapping characters from both ends, advancing inward until the entire string is reversed without extra memory. Learn to implement this efficient O(n) time and O(1) space complexity solution critical 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
