10:03 Lesson 30.6 The Partition algorithm Lesson 30.6 The Partition algorithm	Lesson 30.6 The Partition algorithm In the previous video, we saw that nested loops are causing our sorting algorithms to be slow. To speed things up, we need to get rid of one of these loops. To do that, we will need a special… pivot mark question region end position algorithm thing partition picture left beginning head things idea x. loop function reason k.
