Hi,

I'm failing the third test case: find_enemy("A1","SW","Z9"). My solution suggests ['L', 26] but the autocorrector says the right answer is ['B', 25].

Ok, if I'm at A1 and I have to go backwards then I'm going to B0!! How is that possible with the pictures in the problem where column A is "taller" than column B and the restriction says that 'A1' ≤ coordinates ≤ 'Z9'? I'll be going out of the map.
