Implementations are for learning purposes only. They may be less efficient than the implementations in the Python standard library. Use them at your discretion.

Our goal is to work together to document and model beautiful, helpful and interesting algorithms using code. We are an open-source community - anyone can contribute. We check each other's work, ...

Alce and Bob could program their algorithms and try them out on some sample inputs. For really big inputs, we can ignore everything but the fastest-growing term: T[PTA](N) <= c[PTA] sqrt(N) (where ...
