RT。
贴个code？
#include <iostream>
using namespace std;
int main()
{
	//freopen("in.txt","r",stdin);
	//freopen("out.txt","w",stdout);
	int i,N;
	int year,month,day,hour,minute,second;
	cin>>N;
	for(i=0;i<N;i++)
	{
		scanf("%d/%d/%d-%d:%d:%d",&year,&month,&day,&hour,&minute,&second);
		printf("%02d/%02d/%04d-",month,day,year);
		if(hour == 12)
			printf("12:%02d:%02dpm\n",minute,second);
		else if(hour == 0)
			printf("12:%02d:%02dam\n",minute,second);
		else if(hour > 12)
			printf("%02d:%02d:%02dpm\n",hour-12,minute,second);
		else
			printf("%02d:%02d:%02dam\n",hour,minute,second);
	}
	return 0;
}
