WebApproach (Brute Force) This approach is straightforward. We can check for every pair in the array and if their sum is equal to the given target, print their indices. This kind of Brute Force solution needs to check every possible pair and number of possible pairs in the array = n * (n – 1) / 2. So, in the worst-case, this approach can be slow.
