Suma de elementos de un array, problema

From: "Pablo D." <lists@...>
Date: 2012-09-28 11:44:58 UTC
List: ruby-talk #399827
Hola, estoy empezando con Ruby y estoy haciendo unos tutoriales que
encontr辿 en http://rubytutorial.wikidot.com En el cap鱈tulo que habla
sobre Arrays, uno de los ejercicios propuestos es sumar los elementos
que hay almacenados en un vector.

Hab鱈a planteado el programa de la siguiente manera pero todo el rato
tengo errores que no s辿 como depurar.

1-He creado una funci坦n que suma dos n炭meros para sumar el componente
del array correspondiente m叩s las sumas anteriores.

2-He inicializado el sumador parcial (buffer) como 0, para que en la
primera iteraci坦n se almacene el primero de los componentes del vector.

3-He intentado hacer la suma de los elementos del vector.

------------------------

vect = [1, 2, 3, 4, 5]

def suma(num,buffer)
  suma = num + buffer
return suma
end

parcial=0

vect.each do |vect|
  sumador = suma(vect,parcial)
  parcial = sumador
return sumador
end

--------------------

El error que me da es el siguiente:

unapruebamas.rb:174:in `block in <main>': unexpected return
(LocalJumpError)
        from unapruebamas.rb:171:in `each'
        from unapruebamas.rb:171:in `<main>'

La fila 171 se corresponde con la de VECT.EACH....

Estoy bastante perdido. Agradecer鱈a cualquier tipo de pista :)

Pablo.
