k个服务器,处理n个任务,每个任务有开始时间和过程时间。直接用一个优先队列维护处理器状态即可。。nlogn


#include <cstdio>
#include <cmath>
#include <cstring>
#include <string>
#include <algorithm>
#include <iostream>
#include <queue>
#include <map>
#include <set>
#include <vector>
using namespace std;

double eps=1e-9;
__int64 min(__int64 a,__int64 b)
