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

object Main{
  def main(args:Array[String]) = {
    val in = readLine.split(" ").map(_.toInt)
    val a = in(0)
    val b = in(1)
    val c = a*b
    val o = "odd"
    val e = "Even"
    if(c%2 == 0){
      println(e)
    } else {
      println(o)
    }
  }
