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

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]): Unit = {
  val product = io.StdIn.readLine().split(' ').map(_.toInt).product

    val result = product % 2 match {
      case 0 => "Even"
      case 1 => "Odd"
    }

    println(result)
  }
}
