WebThe sum of the first N natural numbers is given by the formula P ( P + 1) 2. Solving P ( P + 1) 2 = N for P, we get: P = 2 N − P. It's okay for P to be slightly bigger, as we want a rough estimate only. P = 2 N. Therefore, we have at most 2 N distinct values in the array, which allows us to develop an O ( N N) algorithm.
