| ## Description
 | |
| <section id="description"> Внедрите один алгоритм (или более) для вычисления функции <a href="https://en.wikipedia.org/wiki/Gamma function">Gamma</a> ($ \ Gamma $) (только в реальном поле). Гамма-функция может быть определена как: <div style="padding-left: 4em;"> <big><big>$ \ Gamma (x) = \ displaystyle \ int_0 ^ \ infty t ^ {x-1} e ^ {- t} dt $</big></big> </div></section>
