C++ vector time complexity
WebLibraries can implement different strategies for growth to balance between memory usage and reallocations, but in any case, reallocations should only happen at logarithmically growing intervals of size so that the insertion of individual elements at the end of the vector can be provided with amortized constant time complexity (see push_back). WebComplexity Linear on initial and final sizes (destructions, constructions). Additionally, in the range version (1), if InputIterator is not at least of a forward iterator category (i.e., it is just …

WebSep 9, 2024 · keywords: C++, Time Complexity, Vector, Set and Map. Time complexity of find() in std::map. std::map and std::set are implemented by compiler vendors using highly balanced binary search trees (e.g. red-black tree, AVL tree). As correctly pointed out by David, find would take O(log n) time, where n is the number of elements in the container. WebComplexity Linear on the number of elements inserted (copy/move construction) plus the number of elements after position (moving). Additionally, if InputIterator in the range insert (3) is not at least of a forward iterator category (i.e., just an input iterator) the new capacity cannot be determined beforehand and the insertion incurs in additional logarithmic …
