Hit randomize to randomize, and then choose one of the sorting algorithms. The red arrow shows where the computer is looking.
All algorithms have been slowed down so you can see them. Quick sort was slowed down much more than the others. If these algorithms weren't slowed, they would take very little time. Quick sort would take less than a second. When sorting in Java, Quick sort does more than 10 million numbers per second (this does depend on the diversity of integers). Additionally, in scratch, the time cost of swapping is much more than the time cost of comparing, so Selection Sort does better here than on most systems.
