Problem: <image>

You have one chip and one chance to play roulette. Are you feeling lucky?

Output

Print your bet. Your chip must be placed entirely within some square (not on an edge or a corner shared by adjacent squares).

Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
using namespace std::chrono;
using pii = pair<int, int>;
using pll = pair<long long, long long>;
const int magic = 3;
void solve();
void dump(const vector<int>& a) {
  for (int i = 0; i < a.size(); i++) {
    cerr << a[i] << ' ';
  }
  cerr << endl;
}
template <typename T, int N>
void dump(const array<T, N>& a) {
  for (int i = 0; i < a.size(); i++) {
    cerr << a[i] << ' ';
  }
  cerr << endl;
}
int main(int argc, char** argv) {
  ios_base::sync_with_stdio(false);
  cin.tie(0);
  int t = 1;
  while (t--) {
    solve();
  }
  return 0;
}
const int SZ = 210;
void solve() { cout << "black" << endl; }
