You will be given numbers and the task is to return even numbers as they are, but subtract 1 from odd numbers.
So if you get 4 you return 4. If you get 23 you return 22.
Your solution should be 22 or less characters long.

So if you get 3 you return 3. If you get 24 you return 23.
Your solution should be 27 or less characters long.
