ALT A two-panel meme. The top panel shows the Tower of Hanoi puzzle, a children's stacking toy, with the text 'Everyone: it's a game for kids.' The bottom panel is labeled 'Programmers:' and shows a close-up of a chihuahua with a wide-eyed, horrified expression, as if having a traumatic flashback. The joke is that programmers associate the seemingly simple toy with the complex and often difficult topic of recursion, which is a foundational concept in computer science.
