Hello everyone!

I've learning C# and I've seen that the ToUpper and ToLower methods were
not impleted so I've write 2 simple programas that do this.

What do you think about them?


P.D.: Magic is real......... unless declared integer. 
P.D.D.: Para entender lo que es la recursividad, primero hay que
entender lo que es la recursividad.
