Live demos show a ten-person bubble sort demo with 10 volunteers to illustrate stability and the early-exit optimization; comparisons of quick sort, TimSort, shell, insertion show quicksort usually wins but libraries switch to insertion on degenerate inputs. Big-O explanations include O(1), O(n), O(n^2) with the triangular-count example. Dijkstra appears as a pub‑crawl shortest‑path example (and underpins map routing). Levenshtein distance powers deterministic spellcheck suggestions; a JavaScript timeout sort (setTimeout) is presented as a humorous non‑solution.
