Problem: Sort a linked list in O (n log n) time using constant space complexity. Solution: First, the time complexity can reach the O (nlgn) sorting algorithm. There are three common types: heap sorting, Merge Sorting, and quick sorting, For

In addition to providing regular function adapters, the STL standard library also provides two function adapters for member functions. Their main function is to use these adapters, you can directly call its member functions for each element. There

The time complexity of Merge Sorting and heap sorting is O (nlgn), and the time complexity of insert sorting and Bubble Sorting is O (n ^ 2 ), the time complexity of fast sorting is O (nlgn) on average. These sorting algorithms determine the order
