Writing some algorithm:
me: *codes for half an hour*
"hmm... isn't working... wait wtf this isn't right..."
me: *codes for an hour again*
"still not working hmmm... wait what no this isn't supposed to work..."
me: *codes for a few hours*
"still not working God damnit.... it's supposed to work now..."
me after another few hours: MOTHERFUCKER CAN YOU START FCKING WORKING FUUUUUUUUUUU
