WebBehaviour is undefined if < 5 elements on the queue. You can replace this with the below if you want to avoid the Element copy, however in this case be aware that the reference becomes invalid after the referenced element is popped. WebThe reason there is no vector::find is because there is no algorithmic advantage over std::find (std::find is O(N) and in general, you can't do better for vectors). But the reason you have map::find is because it can be more efficient ( map::find is O(log N) so you would always want to use that over std::find for maps).
