Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)

"use strict";

const main = (arg) => {
  const input = arg.trim().split(" ");
  const a = parseInt(input[0]);
  const b = parseInt(input[1]);
  let answer = a * b;
  if (answer % 2 == 0) {
    console.log("Even");
    return;
  }
  console.log("Odd");
};
main(require("fs").readFileSync("/dev/stdin", "utf8"));
// main("1 21");
