I feel exited every time I'm able to look at other people solutions on here, sometimes I spend hours testing other people code and mession around with it, such a grate opportunity.

I felt the exact same way! After submitting my solution (which had taken several hours) triumphantly, I stared in disbelief at the one-liner at the top. And as well as scrolling through all of the other simpler solutions.

You're welcome.
