归并排序(MERGE-SORT)是建立在归并操作上的一种有效的排序算法,该算法是采用分治法(Divide and Conquer)的一个非常典型的应用。将已有序的子序列合并,得到完全有序的序列;即先使每个子序列有序,再使子序列段间有序。若将两个有序表合并成一个有序表,称为二路归并。 时间复杂度分析 从这个递归树可以看出,第...

sort(nodes.begin(),nodes.end(),[](auto&x1,auto&x2)->bool{returnx1.second<x2.second;}); lower bound和upper bound 很多同学对于实现二分非常头疼,好在C++ STL当中也提供了现成的函数可以使用,分别是lower_bound和upper_bound。 这两者都是二分,二分的范围略有区别,lower_bound的定义是找到第一个可...
