#include <iostream>
#include <sched.h>
using namespace std;

int main() {
    int seconds = 0;
    int hour = 0;
    int minute = 0;
    int second = 0;

    cin >> seconds;

    hour = seconds / 3600;
    minute = (seconds % 3600) / 60;
    second = seconds % 60;

    cout << hour << " " << minute << " " << second << endl;

    return 0;
