#Go into iex. Create and run the functions that do the following:
# list_concat.([:a, :b], [:c, :d]) #=> [:a, :b, :c, :d]
# sum.(1, 2, 3) #=> 6
# pair_tuple_to_list.( { 1234, 5678 } ) #=> [ 1234, 5678 ]

defmodule Exercise1 do
  #list_concat = fn a,b -> a ++ b end
  def list_concat(a,b) do
    a ++ b
  end

  #sum = fn a, b, c -> a + b + c end
  def sum(a,b,c) do
    a + b + c
  end

  #pair_tuple_to_list = fn {a, b} -> [a, b]
