@untiy 自己看看，要考虑的点挺多

#include<bits/stdc++.h>
using namespace std;
int main(){
    int s,v;
    cin>>s>>v;
    int t=s/v;
    if(s/v>3590)return 0;
    else if(s%v!=0)t++;
    int m=470-t;
    if(m<0){
        m=1440+m;
        int h=m/60,minn=m%60;
        if(h<10){
            if(minn<10)cout<<0<<h<<":"<<0<<minn;
            else cout<<0<<h<<":"<<minn;
        }
        else{
            if(minn<10)cout<<h<<":"<<0<<minn;
            else cout<<h<<":"<<minn;
        }
    }
    else{
        int h=m/60,minn=m%60;
        if(h<10){
            if(minn<10)cout<<0<<h<<":"<<0<<minn;
            else cout<<0<<h<<":"<<minn;
        }
        else{
            if(minn<10)cout<<h<<":"<<0<<minn;
            else cout<<h<<":"<<minn;
        }
    }
    return 0;
}
