Example of fast search algorithm implemented in Java

This paper describes the fast search algorithm implemented in Java. Share with you for your reference, as follows:

The fast search algorithm can fix the position of a number after the array is completely sorted in each cycle according to the largest number you want to find. Each cycle can fix the position of a number. If the position of the current fixed number matches the number you want to find, it will be returned directly. For example, I want to find the second largest number. If the subscript of a fixed number is 1, it is the number to be found at present.

The code is as follows:
