 Now you can see how sorting algorithms work by watching them in real time. You can change the input size and delay, and when the algorithm is running the `comparisons` and `array access` are updating for a better view. If you want to learn these algorithms, watching their code is a good practice but for a better understanding I also recommend their visualization.
