WebLet us understand the 2-pointer approach to find pair with given sum. Consider the given array (sorted) as. A = [-10, -5, -2, 12, 13] and you need to find a pair with sum = -12. Initially, sum = 3 which is more than -12, thus shifting the end pointer to left. Again, shifting the end pointer to the left. Finally, you get a pair with sum = target.
