WebNov 2, 2014 · Thus, the complexity is O (n * log n) (that is, each iteration takes O (log n) time. If you are just looking for the number of un-ordered pair and the array is sorted in ascending order. You can use this formula n * (n - 1) / 2. Suppose your array has n elements, for example 3 in your case. It will be 3 * 2 / 2 = 3. WebIt was suggested that perhaps the OP meant that all pairs are in the input, not just a set of them as the question says. In that case the algorithm is much easier because it's no longer necessary to check which pairs are allowed. It's not even necessary to generate the set of all pairs; the following pseudocode will do what the OP asked. hubert\\u0027s hair raising adventure
