1, Fundamentals of sorting algorithm 1. Algorithm classification Common sorting algorithms can be divided into two categories: Comparison sort: the relative order between elements is determined by comparison. Because its time complexity cannot exceed O(nlogn), it is also called nonlinear time comparison sort. Non comparison sort: the re ...

Coloring is used to judge whether a graph is a bipartite graph Bipartite graph: all points in the graph can be divided into two sides, so that all edges are between sets, and there are no edges inside the set Properties used: a graph is a bipartite graph if and only if the graph can be dyadic A graph is a bipartite graph if and only if it do ...

1, On constructor 1.1 constructor body assignment When creating an object, the compiler calls the constructor to give each member variable in the object an appropriate initial value class Date { public: Date(int year, int month, int day) { _year = year; _month = month; _day = day; } private: int _year; int _month; ...
