@LLVM_lldb_14_0_0 有的时候会觉得自己被红题玩弄了。

@xiaozhengguo123 你的思路好复杂。

#include<bits/stdc++.h>
using namespace std;

int main(){
//  freopen(".in","r",stdin);
//  freopen(".out","w",stdout);
    int s,v;
    cin>>s>>v;
    int t=s/v;
    if(t*v<s) t++;
    int ans=480-t-10;
    if(ans<0) ans=1440+ans;
    int ansh=ans/60,ansm=ans%60;
    if(ansh<10) cout<<"0";
    cout<<ansh<<":";
    if(ansm<10) cout<<"0";
    cout<<ansm;
    return 0;
}
