Problem Statement

You are given integers A and B, each between 1 and 3 (inclusive).

Determine if there is an integer C between 1 and 3 (inclusive) such that A \times B \times C is an odd number.

Constraints

All values in input are integers.

1 \leq A, B \leq 3

Input

Input is given from Standard Input in the following format:

A B

Output

If there is an integer C between 1 and 3 that satisfies the condition, print Yes; otherwise, print No.

Sample Input 1

3 1

Sample Output 1

Yes

Let C = 3. Then, A \times B \times C = 3 \times 1 \times 3 = 9, which is an odd number.

Sample Input 2

1 2

Sample Output 2

No

Sample Input 3

2 2

Sample Output 3

No

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

'use strict';

function Main(input) {
  const A = Number(input.split('\n')[0].split(' ')[0]);
  const B = Number(input.split('\n')[0].split(' ')[1]);

  if((A * B) % 2 === 0) {
    console.log('No');
  } else {
    console.log('Yes');
  }

};

Main(require("fs").readFileSync("/dev/stdin", "utf8").trim());
