Functional programming is a programming paradigm which models computations (and thus programs) as the evaluation of mathematical functions. It has its roots in lambda calculus, which was developed by Alonzo Church in his research on computability. Functional programming has some interesting conce...

The Unicode Standard is an international standardized character set. It attempts to assign characters and symbols from every writing system a unique number. With every major new version, additional characters are added to the Standard to achieve this goal. In providing a unified character set for ...
