int main()
{
	int month[N]={0,31,28,31,30,31,30,31,31,30,31,30,31};
	int y,m,d,i,sum=0;
	while(scanf("%d/%d/%d",&y,&m,&d)!=EOF)
	{
		for( i=0; i<m; i++ )
		{
			sum=sum+month[i];
		}
		sum=sum+d;
		printf("%d\n",sum);
		sum=0;
	}
	if( y%4==0 && (y%100!=0||y%400==0) );
	{
		sum++;
		printf("%d\n",sum);
	}	
	return 0;
}
求救大佬，就是答案错误0
