AC了

求关

#include <bits/stdc++.h>
using namespace std;
int main() {
    int s, v, h = 8, m = 60, ht, mt;
    cin >> s >> v;
    if (s % v == 0) {
        mt = s / v + 10;
    } else {
        mt = s / v + 11;
    }
    ht = mt / 60;
    mt %= 60;
    if (mt == 0) {
        m = 0;
    } else {
        h--;
        m -= mt;
    }
    if (ht >= 8) {
        h += 24;
    }
    h = h - ht;
    printf("%.2d", h);
    cout << ":";
    printf("%.2d", m);
    return 0;
}
