WebA heap is a way to organize the elements of a range that allows for fast retrieval of the element with the highest value at any moment (with pop_heap ), even repeatedly, while allowing for fast insertion of new elements (with push_heap ). The element with the highest value is always pointed by first. Web(none) Complexity At most log (N) comparisons where N = std::distance(first, last) . Notes A max heap is a range of elements [f, l) that has the following properties: With N = l - f, for all 0 < i < N, f [ (i - 1) / 2] does not compare less than f [i] .
