Solution: Two Sum II - Input Array Is Sorted

Explore how to apply the two pointers technique to solve the Two Sum II problem on a sorted array. This lesson helps you understand the approach of using two indices moving inward to find a target sum efficiently, with a time complexity of O(n) and constant space usage.
