bubble sort is wrong, the time complexity is always n^2

Can you please link the file saying which code is wrong? Is it wrong in all languages? You can open a PR after making a fix.

The bubble sort is wrong in every language. The time complexity of your code is always n^2, the best case should be n. There is an optimization missing.
