@param other [Alimento] @return Alimento type of the class @brief it is a method for know if the node that calls the method it's not equal at the param node.

  return nil unless other.is_a?Alimento #devuelve nil si no son de la clase Alimento los dos objetos
  if valor_calorico == other.valor_calorico
    return 0
  else
    if valor_calorico < other.valor_calorico
      return -1 #devuelve true cuando es menor, y lo niega para conseguirlo negado, el operador < solo comprueba el menor
    else
      return 1 #devuelve true si es >

@return valor @brief it is a method for calculate the AIBC

  aux=[]
  #zip --> coge dos vectores y genera pares, la pos 1 del vector 1 y la pos 2 del vector a los devuelve y los guardo en aux
  #de esta forma tendre en x la pos actual y en y la pos-1 para llevar a cabo la formula
  datos[indice][1..datos[indice].length - 1].zip(datos[indice][0..datos[indice].length - 2]) do |x,y|
    if x < datos[indice][0]

    else
      aux << (((x-datos[indice][0])+(y-datos[indice][0]))/2)*5
    end
  end
  aux.reduce(:+) #sumatorio del vector auxiliar, es lo que devuelve el metodo
