I would like to ask you to verify the following implementation of the PIMPL idiom. In this dummy implementation the stream is read into a string.

This is a Python case insensitive dictionary that is ordered and has integer indexes for the keys and values.
I just wrote it today.
It is ordered because I am using Python 3.9.6 and plain dict is already ordered by default.
It prevents case insensitive duplicate keys from entering the dictionary...
Good day! The task is the following:

I have recently been learning Haskell, and wrote a minesweeper project as an exercise. Here is link to the project.
Basically the code is separated into two parts, the pure part (no monads) and impure part (deals with random and IO). Since I'm pretty new, I'm a little iffy about the whole setup. ...
I recently tried to solve the first non-repeating character problem. Please tell me if my solution is valid. I'm aiming for O(n) with a single loop.
My thinking is, it would be easy to tell you what the last non repeated character is, just:
loop each char
if map[char] doesn't exist
