Challenge Description

Fazer uma função que receba um número inteiro entre 0 e 999 e retorne uma string, que é esse número por extenso em português.

Baby steps: recomendamos que você comece pelos menores números e vá evoluindo o algoritmo até resolver os maiores.

A cada passo que der, tenha testes unitários mostrando o funcionamento, independentemente de estar usando um framework ou não.
