Eight sort algorithms that must be known [java Implementation] (3) Merge sort algorithms and Heap Sort Algorithms
I. Merge Sorting Algorithm
Basic Idea:
The Merge Sorting method combines two (or more) ordered tables into a new ordered table, that is, the sequence to be sorted is divided into several subsequences, each of which is ordered. Then combine the ordered

convergence thresholds until convergence. The HITS algorithm can also be extended to other similar sorting systems.
Hits variants
Most of the problems encountered by the HITS algorithm are because hits is a purely link-based Analysis Algorithm without considering the text content. after kleberger proposed the HITS algorithm, many researchers improved hits and proposed many variant hits algorithms, mainly including:
Improvement on hits by Monika R. he

I. Basic concepts of greedy Algorithms
When a problem has the optimal sub-Structural quality, we will think of using dynamic programming to solve it. But sometimes there are simpler and more effective algorithms. Let's look at an example of coin search. Assume there are four types of coins with

When N is an even number, the median appears at I = n/2 and I = (n + 1)/2 respectively. In this article, we ignore the parity of n. The median indicates the number at I = (n + 1)/2. This document assumes that the numbers in the set are different. Ii. Code
