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.

1 21

Sample Output 2

Odd

As 1 × 21 = 21 is odd, print Odd.

Solution in Ruby (2.7.1) (judge verdict: Wrong Answer)

a = gets.to_i # 指定された入力値を受け取る。
b = gets.to_i # 指定された入力値を受け取る。
# 上記他記述例：a,b = gets.chomp.split.map(&:to_i);

if a * b % 2 == 0 # if文を使ってa×bが2で割り切れるかどうかを判定。
  puts "Even"
else
  puts "Odd"
end
