I decided to write for you some jokes as a reward for your efforts on Codeforces :)

• Why did the bitwise operator feel powerful? Because it could shift anything.

• Why did the dynamic programmer fail his test? He forgot to memorize his answers.

• Why did the recursion go to therapy? It kept calling itself.

• Why don't developers use elevators? They're afraid of infinite loops.

• Why did the debugging session take so long? Because the bug had a recursive nature.

• Why did the competitive programmer get kicked out of the bakery? He kept greedily taking all the bread.

If I succeeded in changing your mood, please give me an upvote :)
