I have a System76 Lemur Pro 10, while the hardware quality is poor (poor speakers, poor quality chassis, poor trackpad), it has been pretty solid otherwise for the last 4 years, with PopOS as my daily driver which I really love.

For work, I use a 2019 MacBook which has great hardware, but I am not a fan of MacOS. Will soon ask for upgrade to an M1. (My perfect laptop would be Apple hardware running PopOS).

My next laptop will likely be a Framework laptop unless System76 rolls out their own hardware which is much much improved than their current lot. I hope my current laptop will probably last 2-3 more years, if not more. (btw I use Steam Deck for gaming needs)

Elixir solution

To run it, you need Erlang and Elixir installed with iex available on path (installation instructions here)

Paste the code in a file with extension .exs (e.g. solution.exs) and run with iex solution.exs.

It prints the output to Standard Output and appends a newline at the end

Please let me know if this method of running code does not work.

defmodule Brackets do
  @pairs %{
    "]" => "[",
    "}" => "{",
    ")" => "("
  }

  def simplify(brackets) do
    brackets
    |> String.trim()
    |> String.graphemes()
    |> Enum.reduce([], &reducer/2)
    |> Enum.reverse()
  end

  defp reducer(c, []), do: [c]

  defp reducer(c, [x | rest] = acc) do
    if @pairs[c] == x do
      rest
    else
      [c | acc]
    end
  end

end

brackets = IO.gets("Please enter your input> ")

brackets
|> Brackets.simplify()
|> IO.puts()

I’ve been studying BSTs recently with the book “Algo & DS in Python by Goodrich-Tamassia”, this article seems to be the next thing to read. Thanks for sharing.

Great idea, looking forward to the first challenge

Thank you so much

yes, not gonna quit without a signed offer letter in hand…

Yes, that crossed my mind. I can also use that time to prepare for interviews while keeping an eye on the job market & pick and choose an opportunity that’s better for me.

Hey thanks for sharing. I’d like to do this in rust too. Did you do the course or the book or both?
