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 Output 2

Odd

As 1 × 21 = 21 is odd, print Odd.

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

object Main {
  def judge(ret: Boolean, ok: String, ng: String): Unit = if (ret) println(ok) else println(ng)

  def main(args: Array[String]): Unit = {
    val sc = new java.util.Scanner(System.in)
    val a, b = sc.nextInt

    val ret = if (a % 2 == 1 && b % 2 == 1) true else false

    judge(ret, "Odd", "Even")
  }
}
