AtCoDeer the deer found two positive integers, a and b. Determine whether the product of a and b is even or odd.

a, b = map(int, input().split())
product = a * b
print('even' if product % 2 == 0 else 'odd')

a, b = map(int, input().split())
product = a * b
print('Even' if product % 2 == 0 else 'Odd')
