// #define debug freopen("in.txt","r",stdin), freopen("out.txt","w",stdout);
#define ZERO 0
#define J 10
#define ONE_HUNDRED 100
#define CHARCTER ""
#define CHARCTER_SPACE " "
#define CHARACTER_LINE_BREAK "\n"
// #pragma GCC optimize("O2")
using namespace std;
int _hundred, _ten, _one, n;
void _Output(int _print, string _plus);

	cout << _print << _plus; }

	ios::sync_with_stdio(false);
	cin.tie(ZERO);
	cout.tie(ZERO);
	cin >> n;
	_hundred = n / ONE_HUNDRED;
	_ten = n / J % J;
	_one = n % J;
	_Output(_one, CHARCTER_SPACE);
	_Output(_ten, CHARCTER_SPACE);
	_Output(_hundred, CHARCTER_SPACE);
	return ZERO; }
