Decided to do one of the exercises from _Programming Elixir_, section 7.5. "Write max(list) that returns the element with the maximum value in the list (This is slightly trickier than it sounds.)" I've got both the max value and the (1-based) index of the max value. My First Elixir Code (aw)!

MyList.ex

defmodule MyList do

  def mymax([h | t]), do: mymax(h, t)

	def mymax(v, []), do: v

	def mymax(v, [h | t]) when h < v, do: mymax(v, t)

	def mymax(_v, [h | t]), do: mymax(h, t)



	def mymaxelem([h | t]), do: mymaxelem(0, 1, h, t)

	def mymaxelem(mx, _ix, _v, []), do: mx + 1

	def mymaxelem(mx, ix, v, [h | t]) when v >= h, do: mymaxelem(mx, ix + 1, v, t)

	def mymaxelem(_mx, ix, _v, [h | t]), do: mymaxelem(ix, ix + 1, h, t)

end
