1.建议用`printf("%02d:%02d",hour,min)`格式化输出。
2.把`if(hour<=0)`改成`if(hour<0)`。

AC CODE:
```cpp
#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
int main()
{
int s,v,t;
cin>>s>>v;
t=s/v;
if(s%v!=0){
t++;
}
int hour=7,min=50;
int t_h=t/60;
int t_m=t%60;
hour-=t_h;
min-=t_m;
if(min<0){
min+=60;
hour--;
}
if(hour<0){
hour+=24;
}
printf("%02d:%02d",hour,min);
return 0;
}
```
