Merge branch 'redo-class2-hw' into 'main'

### Class 2 homework

* Create a merge request for this repo

* It has to come from your fork, and **not** from the main branch

* Feel free to improve some text, reword something, fix a typo, fix a bug in the homework check script (💰)

* Otherwise give us feedback inside session2_feedback/

  * Create a new file `<UCO>.txt`

* MR doesn't need to be merged to pass this homework

* Create a new file in `class2_homework/` subdirectory of this repository with

  a name `<UCO>.txt`. Content of the file is up to you: it can be your

  favourite hobby, a cooking recipe, a book, ...

* Commit the change.

* Push the change to your fork, **not** to the main branch (Hint: imagine a

  merge request would be a next step).

* After you've done all of the above, save your command history, especially all

  `git` binary invocations. Put the history in a new file `<UCO>_commands.txt`

  and place it in the same directory and the same branch, commit it and push

  it. We want to see how you use git so we're sure we're teaching effectively.

  This is how to directory should look:

```bash

$ tree class2_homework/

 class2_homework

 ├── 255490_commands.txt

 └── 255490.txt

 1 directory, 2 files

$ cat class2_homework/*

git foo

git bar

cat dog

My favourite book series now is from Jeffery Deaver: Lincoln Rhyme.

It's so hard to organize and deliver a University course, I learnt so much from this experience.
