应用:使用push_front()函数输入具有以下编号和顺序的空列表,并对给定列表进行排序。 Input: 7, 89, 45, 6, 24, 58, 43 Output:6, 7, 24, 43, 45, 58, 89 // CPP program to illustrate// application Ofpush_front() function#include<iostream>#include<list>usingnamespacestd;intmain(){list<int...
双端队列(deque)和向量没有多少区别。它们主要的区别在性能上:和向量相比,在双端队列起点上的插入和删除操作要快的多,其时间复杂度仅为常数。所有的STL类属方法都可用于双端队列。下面为push_back和push_front函数的列子: 1#include<iostream> 2#include<cassert> 3#include<string> 4#include<deque> 5#includ...
