无视多出来的右大括号qwq

已自行解决，“if(h=0)”应该改为“if(h==0)”
关系运算符搞错，我是蒟蒻
```cpp
#include <bits/stdc++.h>
using namespace std;
int main()
{
int s,v,t,m,h,M=50,H=7;
scanf("%d%d",&s,&v);
t=s/v;
if(s%v!=0) t++;
h=t/60;
if(h==0) m=t;
else m=t%60;
if(M-m<0)
{
H=H-1;
M=M+60;
M=M-m;
}
else
M=M-m;
if(H-h<0)
{
H=H+24;
H=H-h;
}
else H=H-h;
if((H<10)&&(M<10))
printf("0%d:0%d",H,M);
else if((H>=10)&&(M>=10))
printf("%d:%d",H,M);
else if((H<10)&&(M>=10))
printf("0%d:%d",H,M);
else if((H>=10)&&(M<10))
printf("%d:0%d",H,M);
return 0;
}
```
