代码：

#include <bits/stdc++.h>
using namespace std;
long long sum, a, n, s, md;

int main() {
	long long h, m, s, k;
	cin >> h >> m >> s >> k;
	sum = h * 3600 + m * 60 + s;
	sum += k;
	a = sum / 3600;
	if (a % 24 >= 1 && a > 24) {
		md = a / 24;
		a -= (md * 24);
	}
	n = a*60-sum / 60;
	s = sum % 3600;
	cout << a << " " << n << " " << s;
	return 0;
}
