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 JavaScript (node.js v5.12) (judge verdict: Runtime Error)

function main(input) {
    const args = input.split("\n");
    const N = parseInt(args[0],10);
    const nums = args.slice(1,N+1);
    const isValit = nums.every(n=>{
        var ns = n.split(" ");
        var t = parseInt(ns[0]),
            x = parseInt(ns[1]),
            y = parseInt(ns[2])
        var sum = x + y;
        return t >= sum && t % 2 == sum % 2
    })
    if(isValid){
        console.log("Yes");
    }else{
        console.log("No");
    }
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'));
