Flashcards for the interview classic.
Every card names a real algorithm or operation — from Bubble Sort to Dijkstra — and asks one question: how fast is it? Tap one of six complexity classes and the card reveals the answer with a one-line intuition for why.
Filter the deck by topic to drill sorting before an interview, or leave it on All topics for a mixed workout. Your streak sits in the corner and the all-time best survives reloads.
