Hello!
I don't normally do this.
Here is the challenge.
There is a 5 * 5 grid below. THe grid is composed of X's and O's. The spots with O's cannot be passed over with a line. Use a line to link all of the X's. A line cannot be diagonal.

Some people will post real challenges but normally they have a registered account, and some credit to prove they can solve math problems and aren't just cheating. Also, challenges won't be that easy. This is not a challenge this is homework. You can tell because when you search it, it says no results, not even any similar questions that prove it might not be homework. Any person with a brain (not you by the way) can see an easy answer. So how about I leave a challenge for you: see Guest's challenge above, it's quite nice and you should REALLY do it.
