Elixir: Immutability

🚧 In development

Instructions

🚧 In development

The exercise doesn't pass checking. What to do? 😶

If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:

Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.

In my environment the code works, but not here 🤨

My code is different from the teacher's one 🤔

I've read the lessons but nothing is clear 🙄

Прочитал урок — ничего не понятно 🙄

Found a bug? Have something to add? Pull requests are welcome!

Your exercise will be checked with these tests:

defmodule Test do
  use ExUnit.Case
  import Solution

  test "encode/decode" do
    assert encode(~c"Hello", 10) |> decode(10) == ~c"Hello"
    assert encode(~c"12345", 1) == ~c"23456"
    assert decode(~c"12345", 1) == ~c"01234"
    assert encode(~c"abcdef", 2) == ~c"cdefgh"
    assert decode(~c"abcdef", 2) == ~c"_`abcd"
  end

  test "encode/decode with cyrillic symbols" do
    assert encode(~c"Привет", 10) |> decode(10) == ~c"Привет"
    assert encode(~c"Привет мир", 500) |> decode(500) == ~c"Привет мир"
  end
end
