#6 Failure !

“Debugging is twice as hard as writing the code in the first place.

Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it”

Brian Kernighan

Why this way ? Showing off how clever I was… Keep my job ;) However, it’s wrong wrong wrong
