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 1 × 21 = 21 is odd, print Odd.

Solution in Scala (2.13.1) (judge verdict: Accepted)

import java.util.Scanner
object Main extends App{
	val scanner = new Scanner(System.in)
	val a = scanner.nextInt
	val b = scanner.nextInt
	if(a*b % 2 == 1){
		println("Odd")
	}else{
		println("Even")
	}
	scanner.close 
}
