For data structure, has always been the short board of most people, not can’t learn, but easy to forget, so is there a very vivid explanation, let us remember it all of a sudden? The answer is yes.

The following 10 giFs will hopefully give you a deeper understanding of circular, recursive, binary search.

A, circulation
