The problem solved by the 03ZSTI4-01-501 algorithm is very classic, which is to select the k-th largest (k-th smallest) element from a sequence of n elements. Through clever analysis, BFPRT can ensure linear time complexity even in the worst case. The idea of this algorithm is similar to that of quicksort. Of course, in order to achieve a time complexity of o (n) even in the worst case, the five algorithm authors have done a clever job.

Algorithm steps:

·Divide n elements into groups of 5 each, with n/5 (upper bound) groups;

·03ZSTI4-01-501 Take the median of each group and use any sorting method, such as insertion sorting;

·Recursively call the selection algorithm to find the median of all the medians in the previous step, set it as x. In the case of even medians, set it to select the middle one that is smaller;

·Divide the array using x, with k being the number less than or equal to x, and n-k being the number greater than x;
