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>
#include <string.h>
#include <stdlib.h>
int main() {

    char s[12];
    char s1[6];
    char s2[6];
    
    fgets(s, 12, stdin);
    
    sscanf(s, "%s %s", s1, s2);
    
    int a=  atoi(s1);
    int b = atoi(s2);
    
    if(a % 2 == 1 && b%2==1){
        printf("Odd");
    }else{
        printf("Even");
    }

    return 0;
