UVa 12100 (模拟) Printer Queue
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(int pos = , int pri = ):pos(pos), pri(pri) {}
}; int cnt[]; int main()
{
//freopen("in.txt", "r", stdin); int T; scanf("%d", &T);
while(T--)
{
int n, p;
scanf("%d%d", &n, &p);
memset(cnt, , sizeof(cnt));
queue<Task> Q;
for(int i = ; i < n; i++)
{
int pri;
scanf("%d", &pri);
Q.push(Task(i, pri));
cnt[pri]++;
}
while()
{
Task t = Q.front();
int m;
for(m = ; m >= t.pri; m--) if(cnt[m]) break;
cnt[m]--;
if(m > t.pri)
{
while(t.pri != m)
{
Q.pop();
Q.push(t);
t = Q.front();
}
Q.pop();
if(t.pos == p) break;
//printf("sz = %d\n", Q.size());
}
else
{
Q.pop();
if(t.pos == p) break;
}
}
printf("%d\n", n - Q.size());
} return ;
}
