对于输入 `50 1`,您的代码输出 `07:60`,问题出在 `mm = 60 - m;`,当 $m = 0$ 时,需要特殊处理。

```
#include<bits/stdc++.h>
using namespace std;
int main(int argc, char *argv[])
{
int s, v, h, m, hh, mm;
cin >> s >> v;
m = s / v + (s % v != 0) + 10;
h = 8 - (m / 60 + (m % 60 != 0));
m %= 60;
cout << setw(2) << setfill('0') << (h < 0 ? h + 24 : h);
cout << ':';
cout << setw(2) << setfill('0') << (m ? 60 - m: m) << endl;
}

**这道题有好几个坑点,我先说说我的~~失败~~成功经验**
**1.**
数据是49 1时,答案是**07:01**,注意**分钟**和**小时**都要**判断加不加前导零**
**2.**
数据是50 1时答案是**07:00而不是06:60**
**3.**
不要忘记那位yyy~~捡垃圾吃~~垃圾分类的**10分钟**!!!

~~浅浅的吐槽一下,yyy是什么鬼名字啊,还不如叫小明呢~~

AC代码如下(c++)
```c
#include <iostream>
#include <cstdio>
#include <fstream>
#include <algorithm>
#include <cmath>
#include <deque>
#include <vector>
#include <queue>
#include <string>
#include <cstring>
#include <map>
#include <stack>
#include <set>
using namespace std ;
const int S = 10001 ;
int main ()
{
int s , v ;
scanf("%d%d" , &s , &v ) ;
s += v - 1 ;
int ans = 10 + s / v ;
int hour = 0 ;
if(ans >= 60 )
{
hour = ans / 60 ;
ans = ans % 60 ;
}
hour = 7 - hour ;
ans = 60 - ans ;
if(ans == 60)
{
hour ++ ;
ans = 0 ;
}
if(hour < 0 ) hour += 24 ;
if(hour < 10 ) cout << '0' << hour << ":" ;
else cout << hour << ":" ;
if(ans == 0 ) cout << "00" ;
else if(ans < 10) cout << '0' ;
cout << ans ;
return 0 ;
}
