Select sort implementation on arrays.

the _full fat_ one 1 K₡. **You can choose only one of them**.

To both of them you are given some basic tests. You can also have a look at the
code used by the tests and use it to your advantage.

To 2nd and 3rd function you are given a pseudocode that you can use to implement
it.
:::tip Function pointers
In the skeleton of the “full fat” version you might have noticed a weird type
signature of both the `maximum` and `select_sort` functions. Those functions get
passed a _function pointer_ to the comparator that you use for comparing the
respective elements in the passed in array.
If we take the parameter from one of the functions from the skeleton:
```c
int (*comp)(const void *, const void *)
```
`comp` is a function pointer to a function that takes two pointers of unspecified
type, i.e. pure address to the memory (you don't know what stored in there), and
returns an `int`.
You can pass the function by simply using its name. (There is no need to use `&`
to get its address.) And you can also call the function by “calling” the function
pointer, e.g. `comp(left, right)`.

## Submitting
Ideally submit the assignment through the merge request. Step-by-step tutorial is
present [here](../mr). For setting assignee my xlogin is `xfocko`.
For submitting the bonus assignment you can follow the same procedure as for
submitting the homeworks, that is:
In case you do not want to experiment on GitLab, send me the source code via email,
but please prefix subject with: `[PB071/14][seminar-03]`
1. On branch `main` add the provided skeleton.
2. Checkout new branch `seminar-bonus-03`.
3. Add your solution to the newly created branch.
4. Create a MR to the `main` branch with me (`@xfocko`) as the reviewer.
Deadline for the submission of the bonus is **March 27th 24:00**.
:::tip Directory structure for bonuses
Ideally create a directory `seminar-bonuses` in the root of your repository with
bonuses in their own subdirectories.
Structure of your repository can look like this:
```
.
├── bonuses
│ └── seminar-03
├── hello
├── hw01
├── hw02
├── seminar-01
├── seminar-02
└── seminar-03
```
or
```
.
├── bonus-seminar-03
├── hello
├── hw01
├── hw02
├── seminar-01
├── seminar-02
└── seminar-03
```
Structure of the bonuses is entirely up to you, just keep it consistent.
