C++ stl sort time complexity
WebThe C++11 standard guarantees that std::sort has O(n logn) complexity in the worst case. This is different from the average-case guarantee in C++98/03, where std::sort could be implemented with Quicksort (maybe combined with insertion sort for small n), which has O(n^2) in the worst case (for some specific input, such as sorted input). WebOct 24, 2024 · C++ is a general-purpose, object-oriented programming language that was developed as an extension of the C language.C++ was created by Bjarne Stroustrup in 1983 while working on his PhD thesis at Bell Labs.
