Answer 1

IO.inspect dict = Map.new([elixir: 1, java: 3, c: 5, python: 2])

IO.puts "\nkey values:"
Enum.each(dict, fn {k, v} -> IO.puts "#{inspect k} - #{v}" end)

IO.puts "\nkeys:"
Enum.each(Map.keys(dict), fn key -> IO.inspect key end)

IO.puts "\nvalues:"
Enum.each(Map.values(dict), fn value -> IO.inspect value end)
