Best problems — $$$\Theta(thinking)$$$, $$$\Theta(thinking+log(writing))$$$, $$$\Theta(thinking+log(knowledge))$$$, $$$\Theta(thinking+log(knowledge)+log(writing))$$$
Good problems — $$$\Theta(thinking+writing+log(knowledge))$$$, $$$\Theta(thinking+reading+log(knowledge))$$$, $$$\Theta(thinking+reading+writing+log(knowledge))$$$
Nice problems — $$$\Theta(thinking+knowledge)$$$, $$$\Theta(thinking+knowledge+writing)$$$,$$$\Theta(thinking+knowledge+writing+reading)$$$
Mediocre problems — $$$\Theta(thinking+reading)$$$, $$$\Theta(knowledge+writing)$$$
Bad problems — $$$\Theta(reading+writing)$$$, $$$\Theta(reading+log(writing))$$$, $$$\Theta(knowledge)$$$
Hell — $$$\Theta(reading)$$$
I know you were trying to be funny, but the meme doesn't make any sense.
