-1. Crea una función llamada `two_digits()`. Dado un entero de dos dígitos,`two_digits()` devuelve su dígito izquierdo (las decenas) y luego su dígito derecho (las unidades). Utiliza el operador de división de enteros para obtener el dígito de las decenas y el operador de residuo/resto para obtener el dígito de las unidades.
