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 C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>
//#define DEBUG

int main()
{
	long int a,b;
	scanf("%ld%ld",&a,&b);
#ifdef DEBUG
	printf("%ld %ld\n",a,b);
#endif
	if((a*b)%2) printf("Odd\n");
	else        printf("Even\n");
	fflush(stdout);

	return 0;
