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>
#pragma GCC optimize("Ofast")
#pragma loop_opt(on)
#pragma GCC optimize("unroll-loops,no-stack-protector")
#pragma GCC target("sse,sse2,sse3,ssse3,sse4,popcnt,abm,mmx,avx,tune=native")
using namespace std;
signed main() {
  long long n;
  cin >> n;
  if (n == 1 || n == 3 || n == 5 || n == 7 || n == 9 || n == 12 || n == 14 ||
      n == 16 || n == 18 || n == 19 || n == 21 || n == 23 || n == 25 ||
      n == 27 || n == 30 || n == 32 || n == 34 || n == 36)
    cout << "RED\n";
  else
    cout << "BLACK\n";
