Finding three elements in an array whose sum is closest to a given number
...A, but now you don't need the target value anymore.
Clearly, if we simply test all possible 3-tuples, we'd solve the problem in O(n3) -- that's the brute-force baseline. Is it possible to do better? What if we pick the tuples in a somewhat smarter way?
