+ * QuickSort is a divide-and-conquer sorting algorithm.
+ *
+ * <p>The algorithm selects a pivot element and partitions the array into two
+ * subarrays such that:
+ * <ul>
+ *   <li>Elements smaller than the pivot are placed on the left</li>
+ *   <li>Elements greater than the pivot are placed on the right</li>
+ * </ul>
+ *
+ * <p>The subarrays are then recursively sorted until the entire array is ordered.
+ *
+ * <p>This implementation uses randomization to reduce the probability of
+ * encountering worst-case performance on already sorted inputs.
+ *
+ * <p>Time Complexity:
+ * <ul>
+ *   <li>Best Case: O(n log n)</li>
+ *   <li>Average Case: O(n log n)</li>
+ *   <li>Worst Case: O(n^2)</li>
+ * </ul>
+ *
+ * <p>Space Complexity: O(log n) due to recursion stack (in-place sorting).
