The World of YouTube Bubble Sort Algorithm Dancing
theodp writes In addition to The Ghost of Steve Jobs, The Codecracker, a remix of 'The Nutcracker' performed by Silicon Valley's all-girl Castilleja School during Computer Science Education Week earlier this month featured a Bubble Sort Dance. Bubble Sort dancing, it turns out, is more popular than one might imagine. Search YouTube, for example, and you'll find students from the University of Rochester to Osmania University dancing to sort algorithms. Are you a fan of Hungarian folk-dancing? Well there's a very professionally-done Bubble Sort Dance for you! Indeed, well-meaning CS teachers are pushing kids to Bubble Sort Dance to hits like Beauty and a Beat, Roar, Gentleman, Heartbeat, Under the Sea, as well as other music.
It's usually mentioned in CS courses because the first stage in introducing these classes is "think about sorting some numbers - how do you go about doing it", and generally Bubble Sort is the first formalisation that falls out of that. The fact that Selection Sort is the one that you think of is neither here nor there - most students come up with something looking like bubble sort.
It entirely depends on the order of data in the database. If you know the data is already mostly sorted, then it can perform much better than other methods.
