Problem Statement

AtCoDeer the deer found two positive integers, a and b.
Determine whether the product of a and b is even or odd.

Constraints

1 ≤ a,b ≤ 10000

a and b are integers.

Input

Input is given from Standard Input in the following format:

a b

Output

If the product is odd, print Odd; if it is even, print Even.

Sample Input 1

3 4

Sample Output 1

Even

As 3 × 4 = 12 is even, print Even.

Sample Input 2

1 21

Sample Output 2

Odd

As 1 × 21 = 21 is odd, print Odd.

Solution in Scala (2.11.7) (judge verdict: Accepted)

object Main{
  def main(args: Array[String]){
    if (sys.env.getOrElse("TEST", "")=="1"){

    }else{
      val input=io.Source.stdin.getLines().mkString("\n");
      println(solve(input).trim());
    }
  }


  def solve(input:String):String={
    if(input.split(" ").map(_ .toInt).product %2 == 0){"Even"}else{ "Odd"}
  }
}
