```
#include<bits/stdc++.h>
using namespace std;
signed main()
{
int a,b,c,d,e,f;
cin >> a >> b >> c >> d;
e=[(60-b)+(c-(a+1))+(d-0)]/60;
f=[(60-b)+(c-(a+1))+(d-0)]%60;
cout << e << " " << f << endl;
return 0;
}
```
这是原版。。。（没过）

A了
```c
#include<bits/stdc++.h>
using namespace std;
signed main()
{
int a,b,c,d,e,f;
cin >> a >> b >> c >> d;
if (b > d){
e = c - 1 - a;
f = d + 60 - b;
cout << e <<" "<< f << endl;
}
else{
e = c - a;
f = d - b;
cout << e <<" "<< f << endl;
}
return 0;
}
```

细节露太多了吧

```c
if (b > d)
e = c - 1 - a;
f = d + 60 - b;
cout << e << f << endl;
else
e = c - a;
f = d - b;
cout << e << f << endl;
```
加上大括号，加上空格改为：
```
if (b > d){
e = c - 1 - a;
f = d + 60 - b;
cout << e <<" "<< f << endl;
}
else{
e = c - a;
f = d - b;
cout << e <<" "<< f << endl;
}
```

能不关注一下我，我会回关

还有一种简单写法，我写AC的
```c
#include<bits/stdc++.h>
using namespace std;
int main()
{
int a,b,c,d;
scanf("%d %d %d %d",&a,&b,&c,&d);
int e=(c-a)*60+d-b;
printf("%d %d",e/60,e%60);
return 0;
}
```
