Solution in JavaScript (Node.js 12.16.1) (judge verdict: Accepted)

function Main(input) {
  const lines = input.split('\n');
  const [a, b] = lines[0].split(' ').map(s => parseInt(s));
  const n = a * b / 2;
  const judge = n.toString().includes('.');
  console.log(judge ? 'Odd' : 'Even');
}
Main(require("fs").readFileSync("/dev/stdin", "utf8"));
