                    <h3>How it works</h3>
                    <p>Selection Sort finds the <b>smallest element</b> in the list and moves it to the correct
                        position,
                        one step at a time, like selecting the best items from a messy shelf.</p>
                    <ul>
                        <li>
                            <p>🔹 Search through the list to find the smallest item → Swap it with the first unsorted
                                position → Repeat until sorted.</p>
                        </li>
                        <li>
                            <p>🔹 Best & worst case: Always <b>O(n²)</b> since it searches the entire list every time.
                            </p>
                        </li>
                        <li>
                            <p>🔹 Why learn it? It's easy to understand and doesn't need extra memory.</p>
                        </li>
                    </ul>
                    <p>👀 Think of it as: Picking the shortest friend in a line and moving them to the front.</p>
