WebSince C++11, the complexity of the size member function is constant for all standard containers.. std::forward_list which is an implementation of the singly linked list data structure does not provide a size member function. The size can be calculated in linear time using the iterators. Aside from standard C++ containers, all data structures can be … WebOct 8, 2012 · std::set is commonly implemented as a red-black binary search tree. Insertion on this data structure has a worst-case of O (log (n)) complexity, as the tree is kept balanced. Things do not get shifted over when inserting to a set. It is usually not stored as a vector or array, but rather a binary tree.
