<p>This assignment has two versions. For the light version you can get 1.5 K₡. For
the <em>full fat</em> 3 K₡. <strong>You can choose only one of them</strong>.</p>
<p>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.</p>
<p>Details can be found in the doxygen comments included in the source files.</p>

<p>For the light version you have 3 functions to finish:</p>
<ol>
<li><code>swap</code> - that swaps two ints passed by pointers.</li>
<li><code>maximum</code> - that returns index of the biggest <code>int</code> in the array.</li>
<li><code>select_sort</code> - that sorts passed array using Select Sort.</li>
</ol>

type, i.e. pure address to the memory (you don't know what stored in there), and
returns an <code>int</code>.</p><p>You can pass the function by simply using its name. (There is no need to use <code>&</code>
to get its address.) And you can also call the function by “calling” the function
pointer, e.g. <code>comp(left, right)</code>.</p></div></div>

<p>For submitting the bonus assignment you can follow the same procedure as for
submitting the homeworks, that is:</p>
<ol>
<li>On branch <code>main</code> add the provided skeleton.</li>
<li>Checkout new branch <code>seminar-bonus-03</code>.</li>
<li>Add your solution to the newly created branch.</li>
<li>Create a MR to the <code>main</code> branch with me (<code>@xfocko</code>) as the reviewer.</li>
