#include <bits/stdc++.h>
using namespace std;
typedef struct
{ char name[20];
int time;
} stu;
stu a[200000];
bool cmp(stu a,stu b)
{ return a.time>b.time||a.time==b.time&&strcmp(a.name,b.name)>0;
}
int main()
{ int n,i,j,h,m,h0,m0;
scanf("%d%d:%d",&n,&h0,&m0);
m0+=60*h0;
for(i=0; i<n; i++)
{ scanf("%s%d:%d",a[i].name,&h,&m);
a[i].time=60*h+m;
}
//cout<<"============\n";//此行可删去
sort(a,a+n,cmp);
for(i=0; a[i].time>m0; i++)
printf("%s %d:%02d\n",a[i].name,a[i].time/60,a[i].time%60);
return 0;
}
追问不行啊，网站评测只有20分，有些地方不对。追答
把<打错了方向。已经改过来了：
#include <bits/stdc++.h>
using namespace std;
typedef struct
{ char name[20];
int time;
} stu;
stu a[200000];
bool cmp(stu a,stu b)
{ return a.time>b.time||a.time==b.time&&strcmp(a.name,b.name)<0;
}
int main()
{ int n,i,j,h,m,h0,m0;
scanf("%d%d:%d",&n,&h0,&m0);
m0+=60*h0;
for(i=0; i<n; i++)
{ scanf("%s%d:%d",a[i].name,&h,&m);
a[i].time=60*h+m;
}
//cout<<"============\n";//此行可删去
sort(a,a+n,cmp);
for(i=0; a[i].time>m0; i++)
printf("%s %d:%02d\n",a[i].name,a[i].time/60,a[i].time%60);
return 0;
}
