题意:一堆文件但只有一个打印机,按优先级与排队顺序进行打印.也就是在一个可以插队的的队列里,问你何时可以打印到.至于这个插队啊,题目说"Of course, those annoying term papers that others are printing may have to wait for quite some time to get printed, but that's life."嗯,这就是生活. 代码:(Accepted, 0ms) //UVa12100 - Pri…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1972 题目意思:需要模拟打印机打印.打印机里面有一些 job,每个job被赋予1-9的其中一个值,越大表示优先级越高,越早被打印.job这个队列是会向前推进的,如果排在最前面的job优先级最高,那么才打印,否则就把这个job放到队列最后.问给出 m 这个位置的job要经过多长时间才被打印. 规定每次打印时间为一分钟,移动 job到队列最后不占时间. 练开优先队列就继续吧---不过这题不是咯. 仅仅用…

用一个队列模拟,还有一个数组cnt记录9个优先级的任务的数量,每次找到当前最大优先级的任务然后出队,并及时更新cnt数组. #include <iostream> #include <cstring> #include <algorithm> #include <cstdio> #include <queue> using namespace std; struct Task { int pos, pri; Task(, ):pos(pos),…

题目描述: 题目思路: 使用一个队列记录数字,一个优先队列记录优先级,如果相等即可打印: #include <iostream> #include <queue> using namespace std; int main(int argc, char *argv[]) { int t; cin >> t; while(t--) { int n,pos; queue<int> q ; priority_queue<int> pq ; cin &g…

题目很简单,给一个队列以及文件的位置,然后一个一个检查,如果第一个是优先级最高的就打印,否则放到队列后面,求所要打印的文件打印需要花费多长时间. 这里我用数组模拟队列实现,考虑到最糟糕的情况,必须把数组开到maxn*maxn.另外当所要打印的文件优先级不是最高的时候也需要排列到后面. 0.016s. 代码: #include <cstdio> const int maxn = 101; int t, n, m, time; int q[maxn*maxn]; int print() { int…

题意:有多组数据,每组数据给出n,m,n表示需要打印的文件个数,m表示要打印的目标位置(m为0~n-1).    接下来给出n个数,第i个值对应第i-1个位置的优先级大小.    打印规则如下:    将队列中的第一个打印工作J从队列中取出:    如果在队列中有优先级高于J的打印工作,则不打印J,将J移到队列最后端:    否则打印J.    每打印一个需要1分钟,问到目标文件被打印完成需要多少分钟. #include <iostream> #include <stdio.h>…

传送门:https://uva.onlinejudge.org/external/121/12100.pdf 题意:队列中待打印的任务(1 <= n <= 100)带有优先级(1-9), 打印步骤为每次从队首拿出一个, 如果队列中没有优先级比该任务高的, 打印这个任务; 若有优先级高的, 把这个任务放到队尾,  并打印优先级最高的. 每打印一次耗时1分钟, 求给定任务什么时候打印. 水题A半天    不愧是弱渣.......... 最坏的情况需要maxn*maxn的空间........ fro…

因为实验室有个多余的老服务器,所以近段时间想把老服务器做成打印机服务器,同时因为最近在学习linux,所以就像在CentOS6.3 上安装打印机驱动.因为是新手,所以走了不少弯路,今天终于把打印机安装好了. 网上现在流传各种安装方法,本人试了不少,可惜成功的机会没有,下面就唯一成功的一个写出来,希望有需要的人少走些弯路. 我用的是foo2zjs驱动,它现在支持不少的打印机,其中就包括我的1020. 我是做成打印机服务器,所以选用cups,而不用samba,因为本人不会sanmba. 首先确认机器…
