Description of Java Merge Sorting Algorithm, Bubble Sorting Algorithm, selection sorting algorithm, insertion sorting algorithm, and quick Sorting Algorithm

Algorithm Is a set of clearly defined rules used to solve a problem within a limited step. In layman's terms, it is the process of solving computer problems. In this process, no matter whether it is a problem-solving idea or writing Program All are implementing certain algorithms. The former is an algorithm implemented by reasoning, and the latter is an algorithm

Page replacement algorithm (best permutation algorithm, FIFO permutation algorithm, LRU permutation algorithm, lfu permutation algorithm)

Page substitution occurs because of paged-request storage management, which is one of the ways to implement virtual storage management, where one feature is multiple--and multiple times the page is swapped in or out of memory.Best-performing page replacement algorithm: the best permutation algorithmThe more commonly used page substitution algorithms are: FIFO permutation algorithm, LRU permutation

Data structure and Algorithm learning path: lis--dynamic programming algorithm for maximum increment sequence and binary thought algorithm _ Data structure and algorithm

someone asked, why is F (x-1) +1 and 1 compared AH. The reason is simple: take F (2) as an example, F (2) =f (1+1), and f (1) = 1, that is, the result of F (2) is associated with F (1), whereas F (2) itself has an initial value of 1, the final value of F (2) According to the question is supposed to be through F (1) The value of the operation and its initial value select the larger one. And so on in the back. 2, this method is very ingenious, the main idea is this, I don't care what your sequen

If traversal is fast, you can directly call AddTest to add one more time. If the query is fast, you can use KindOfTestNeed to extract the query conditions, the results generated by the current code are the same each time. If there is a real library, you can use the Randomization of the query results and the Randomization of the KindOfTestNeed condition to g
