@isahdggd222 我的代码

#include<bits/stdc++.h>
using namespace std;
int main()
{
    double s,v;
    cin>>s>>v;
    int m=8*60+24*60;
    int t=ceil(s/v)+10;
    m=m-t;
    if(m>60*24)
    m=m-60*24;
    int g=m%60;
    int h=ceil(m/60);
    if(h<10)
    {
        if(g<10) cout<<"0"<<h<<":0"<<g;
        else cout<<"0"<<h<<":"<<g;
    }
    else
    {
        if(g<10) cout<<h<<":0"<<g;
        else cout<<h<<":"<<g;
    }
}

@isahdggd222

#include<bits/stdc++.h>
using namespace std;
int main(){
    int s,v,h,m=0;
    cin>>s>>v;
    int t=ceil(1.0*s/v)+10;//ceil是上取整
    int from_zero=60*32-t;//距离前一天的凌晨
    h=(from_zero/60)%24;
    m=from_zero%60;
    printf("%02d:%02d",h,m);
