Subject: Array Number of Leaves

Dear Rubyist,

I want to count array list [1,2,3,[4],5] ---> # 5 leaves
but I always get sum_of_array.

Where did I do wrong?


	def array_leave1 # sum_of_array?
		res = 0
		self.each{|elem|
			if elem.kind_of?(Array)
				res += elem.sum_of_array
			else
				res += elem
			end
		}
		return res
	end

def number_of_leaves
    self.inject(0){|acc,x|
        if x.kind_of?(Array)
          acc += x.number_of_leaves
        else
          acc += x
        end
      }
  end

many thanks in advance.

regards,
salai
