Problem Statement

Implement one algorithm (or more) to compute the Gamma (

Γ

{\displaystyle \Gamma }

) function (in the real field only). If your language has the function as built-in or you know a library which has it, compare your implementation's results with the results of the built-in/library function. The Gamma function can be defined as: This suggests a straightforward (but inefficient) way of computing the

Γ

{\displaystyle \Gamma }

through numerical integration.
