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>…

题目链接:http://poj.org/problem?id=3253 思路分析:题目与哈夫曼编码原理相同,使用优先队列与贪心思想:读入数据在优先队列中,弹出两个数计算它们的和,再压入队列中: 代码如下: #include <iostream> #include <queue> using namespace std; struct cmp { bool operator() (long long a, long long b) { return a > b; } }; in…

2013-08-08 POJ 3481  Double Queue 这个题应该是STL里较简单的吧,用平衡二叉树也可以做,但是自己掌握不够- -,开始想用两个优先队列,一个从大到小,一个从小到大,可是因为它又可能删除优先权最大的,又可能删除优先权最小的,所以当输入为2或者3的时候没办法判断是不是没有顾客了.通过这道题发觉map的其他用法真的是一点不会.所以看了别人的代码用了两种方法试着敲一下,写这个随笔是博客的第一篇文章,内容虽然这么水,但是的确是我之前掌握不好的部分,本菜鸟今天比赛之后受刺激了…
