Thinking when sleepy

[ZaidAlyafey]

I was writing a code for a problem and I spent around an hour on it (thinking I am really solving it ) then discovering that was just a waste of time because I am not thinking right . I need to go to sleep .

I'm always doing that. I get to the point where I'm too stupid to know that I need to go to bed!

This happened to me recently, it was late at night and I was trying to come up with some algorithm to solve a problem and failing, I did not understand why, everything checked out..

Turns out the problem I was trying to solve had, in fact, no solution, and provably so. I didn't feel so smart afterwards.. it's sad because I should have realized that instantly

Three hours of my life I'll never get back /sigh

There is a way I think when My answer does not match with facit...
1.I need to sleep..
2. Facit is wrong
and no there is no option 3
