可以用stl中的map 因为map本身就根据key的值排了序 对应2,3 我们只需要输出最大或最小就行了并从map中删除该键值 #include<cstdio> #include<map> using namespace std; map<int, int> a; int main() { map<int, int>::iterator it; int n,k,p; while (scanf

思路:虽然是个SBT的裸题,不过用set也是可以水过的 #include<iostream> #include<cstdio> #include<cstring> #include<set> #include<vector> using namespace std; int main() { set<pair<int,int> >s; set<pair<int,int> >::iterator it; int p,k,n; while(scanf("%d",&n)!=EOF && n) { i...
POJ 3481 Double Queue(STL) 题意 模拟银行的排队系统 有三种操作 1-加入优先级为p 编号为k的人到队列 2-服务当前优先级最大的 3-服务当前优先级最小的 0-退出系统 能够用stl中的map 由于map本身就依据key的值排了序 相应2。3 我们仅仅须要输出最大或最小即可了并从map中删除该键值 #include<cstdio>#i...
Furthermore, we develop three effective algorithms for computing the performance measures (i.e., the probabilities of stationary queue lengths, the average stationary queue lengths, and the average sojourn times) of the double-ended queue with non-Poisson inputs. Finally, we use some numerical ...
简介:双端队列(Deque,全称:Double-ended Queue)是一种线性数据结构,它允许在队列的两端进行插入和删除操作。与普通队列(只能在尾部插入,在头部删除)和栈(只能在尾部插入,在头部删除)不同,双端队列可以在两端进行插入和删除操作。 双端队列(Deque,全称:Double-ended Queue)是一种线性数据结构,它允许在队列的两端进...
POJ 3481 Double Queue 给你0-3四个指令: 0 退出 1 添加优先级为P 的 K值,进入队列 2 最高优先级出队 3 最低优先级出队 64520 小心double的比较 对于double的比较,存在一些可能的坑,大家应该都清楚。比如容易注意的是double==double的精度问题。...NaN: {0}", Double.NaN == Double.NaN); Console....

A queue represents a data structure that adheres to the principle of FIFO (First-In-First-Out), meaning that the item that enters first will be the first to exit. Deletion occurs at the front end or head of the queue, while insertion takes place at the rear end or tail. An instance...
