In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Quick sorting uses the idea of divide-and-conquer.

Then the two parts of the sequence are sorted according to the same algorithm respectively, until the sequence is ordered as a whole.

Take the following sequence arr as an example to sort in ascending order to illustrate the basic algorithm of fast sorting.

The value 23 of the first position is used as the base value base, and the comparison starts from the right, if arr [high] > base,high moves forward.

Arr [high]
