#### #include <iostream>
using namespace std;
int main()
{
int a,b,c,d;
cin>>a>>b>>c>>d;
int x=c-a,y=d-b;
if(y<0){x--;y+=60;}
cout<<x<<" "<<y;
return 0;

int main(){ int a,b,c,d,f,e,sum; scanf("%d%d%d%d",&a,&b,&c,&d); e=a60+b; f=c60+c; sum=f-e; printf("%d,%d\n",sum/60,sum%60); return 0;
} 感觉思路没错，大佬看看哪里有问题
