看到代码长度的时候我沉默了......

这不会代码长度超长么（）

@72728abcd 其实很简单，只需要建立两个变量分别来存储小时数和分钟数即可，不过还需要特判小时数和分钟数是为零的情况，最后按要求输出就行了。
AC Code:(建议参考后自行写出)
#include <bits/stdc++.h>
using namespace std;
int s, v, h = 7, m = 50;
int main()
{
scanf("%d%d", &s, &v);
m -= ceil(s * 1.0 / v);
while (m < 0)
{
h -= 1;
m += 60;
}
while (h < 0)
{
h += 24;
}
printf("%.2d:%.2d\n", h, m);
return 0;

@72728abcd 建议用 printf 格式化输出，起码每个位置能省 10 行
