I once had a professor ask to solve the tower of hanoi using only 2 pegs.

Oh god Hanoi's towers... Incredible that I programmed it in BASIC on my ZX81 in the 80s, and now at 50+yo I would have no clue how to program it lol

Any other recursive algorithm was no problem for me, but I couldn't wrap my head around this game.

This is called Tower of Hanoi problem, usually introduced as main task when learning about recursion in programming

The meme basically shows how a non-programmer sees the Towers of Hanoi game as a fun little puzzle, while a programmer sees it as a traumatizing experience due to the recursive nature of the algorithm behind it

Good ol' emacs, relevant xkcd (although I don't think there's anyone that hasn't seen it).
