Reverse an Array
đ Problem
Given an array of numbers, reverse it in place â the last element should become the first, and so on.
đ§ Approach
Use two pointers: one starting at the beginning (left) and one at the end (right). Swap the elements they point to, then move left forward and right backward. Stop when left crosses right â this way you reverse the array without needing extra memory.
