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]) {
    val sc = new java.util.Scanner(System.in);
    val a, b = sc.nextInt;
    println(calc(a * b));
  }

  def calc(pro:Int) : String = {
    if (pro % 2 == 0) "Even" else "Odd"
  }
}
