<时间推进>题解

这道题比较简单，上代码

#include <iostream>
using namespace std;

int main() {
    long long H, M, S, K;
    cin >> H >> M >> S >> K;
    
    long long total = H * 3600 + M * 60 + S + K;
    total %= 86400;
    
    H = total / 3600;
    M = (total % 3600) / 60;
    S = total % 60;
    
    cout << H << " " << M << " " << S << endl;
    return 0;
}
