Find all pairs with a given sum | SDE Sheet | Hashing

In this video we will see how to find all pairs from two unsorted arrays of distinct elements, whose sum is equal to X. Examples: Input : arr1[] = {-1, -2, 4, -6, 5, 7} arr2[] = {6, 3, 4, 0} x = 8 Output : 4 4 5 3 Check out the video to see how we implement this!!
