elixir 二：循环list求和

 1 defmodule DemoTest do
 2   def f do
 3     IO.puts("cccc")
 4   end
 5 
 6   def testRecursion([], n) do
 7     n
 8   end
 9 
10   def testRecursion(msg, n) do
11     testRecursion(tl(msg), hd(msg) + n)
12   end
13 end
14 
15 a = [1,2,3]
16 b=DemoTest.testRecursion(a, 0)
17 IO.puts(b)

官方例子：

1  def sum_list([head | tail], accumulator) do
2     sum_list(tail, head + accumulator)
3   end
4 
5   def sum_list([], accumulator) do
6     accumulator
7   end
