希望你能看懂

#include<bits/stdc++.h>
using namespace std;
int main () {
    int s,u;
    int minute = 0;
    int hour = 0;
    cin >> s >> u;
    int time = s / u;
    if (time * u != s) {
        time++;
    }
    hour = time / 60;
    minute = time % 60;
    if (minute > 50) {
        minute -= 50;
        hour++;
        minute = 60 - minute;
    }
    else {
        minute = 50 - minute;
    }
    if (hour > 7) {
        hour -= 7;
        hour = 24 - hour;
    }
    else {
        hour = 7 - hour;
    }
    if (hour < 10) {
        cout << "0";
    }
    cout << hour << ":";
    if (minute < 10) {
        cout << "0"; 
    }
    cout << minute << endl; 
    return 0;
}
