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 Lua (5.3.2) (judge verdict: Runtime Error)

local n = io.read("*n")
local str = {}
for i = 1, n do
    print(io.read("l"))
    table.insert(str, io.read("l"))
end
local firStr = str[1]
local len = string.len(firStr)
local endStr = string.sub(firStr, len, len)
local tab = {}
tab[firStr] = 1
local result = true
for i = 2,n do
    local tStr = str[i]
    local t = string.sub(tStr, 1, 1)
    if t == endStr or tab[tStr] then
        print("No")
        result = false
        break
    end
    len = string.len(tStr)
    endStr = string.sub(tStr, len, len)
end
if result then
    print("Yes")
end
