```由于路途遥远，yyy 可能不得不提前一点出发，但是提前的时间不会超过一天。```

```cpp
if(time<0)
{
g--;
time+=60;
}
```
改成
```cpp
while(time<0)
{
g--;
time+=60;
if(g<0) g+=24;
}
```

还有
```cpp
if(time>=10){
printf("0%d:%d",g,time);
}
else
printf("0%d:0%d",g,time);
```
改成
```cpp
if(time>=10){
if(g<=10) printf("0%d:%d",g,time);
else printf("%d:%d",g,time);
}
else{
if(g<=10) printf("0%d:0%d",g,time);
else printf("%d:0%d",g,time);
}
```

@[wugui10086](/user/916513) az,我贴一下自己的代码,您看着自己改一下吧
```cpp
#include<stdio.h>
int main(){
int h,m,x,y,s,v,i;
scanf("%d%d",&s,&v);
if(s%v==0) i=10+s/v;
else i=11+s/v;
if(480-i<0){
x=1440+(480-i);
h=x/60;
m=x%60;
}
else{
y=480-i;
h=y/60;
m=y%60;
}
if(h>=10){
if(m>=10) printf("%d:%d",h,m);
else printf("%d:0%d",h,m);
}
else{
if(m>=10) printf("0%d:%d",h,m);
else printf("0%d:0%d",h,m);
}
return 0;
}
```
