algorithms in nutshell

A difficult question about algorithms, writing inverse Algorithms Reprint Source: http://blog.liutaotao.com/blogview.asp? Logid = 38 Recently I have been studying the compression algorithm. I just learned a compression algorithm and transformed it into a test question.This question is very difficult, and this algorithm is very clever. If I do not know the answer, I am not sure I can do it.If you are confide

Programming algorithms and AlgorithmsK-way merge sort code (C ++) Address: http://blog.csdn.net/caroline_wendy K-path Merge SortingAs a classic external sorting algorithm, programmers must master it. Knowledge Concept reference: Main Ideas: In k sorted files, select the first value, use the loser tree, update the binary tree structure, and finally select the optimal value. The code is for reference only. For example, the minimum value is replaced

[Introduction to algorithms] 12th skip table, Introduction to algorithms skip This section introduces a new data structure-Skip table. A skip table is a simple and interesting data structure for dynamic search. It is easy to implement and ensures efficient performance, namely 2 * O (lgn) search Performance Before that, I would like to talk about the linked list. The advantage of the linked list is that it

10 sort algorithms (code and description) and 10 sort Algorithms 1. Bubble Sorting The basic idea is to compare the key words of adjacent records in two or two pairs. If the reverse order is used, the key words are exchanged. The best case of Bubble Sorting time complexity is O (n), and the worst case is O (n ^ 2) Improvement Method 1: Set the flag bit. Obviously, if there is no switching (flag = false), th

[Introduction to algorithms] Lesson 10 balanced search tree and introduction to Algorithms If the tree structure cannot be balanced, the search performance will be greatly compromised. This section introduces several classic balancing trees, such as AVL, 2-3-4tree, and red/black tree, then I focused on the red and black trees. Next I will give a brief summary of the basic nature of the red and black trees.

Algorithms-Meanings of mathematical terms and mathematical terms in discrete mathematics, and answers to discrete mathematics and Algorithms Here we will introduce two important functions in discrete mathematics: The base function and the top function. Make x a real number. The base function rounds x to an integer smaller than or equal to x and closest to x, while the top function rounds x to an integer gr

Quick sorting (Quick sort)Start by selecting one of the data (usually the first number of the array) as the key data, and then putting all the smaller numbers in front of it, all the larger numbers are placed behind it, this process is called a quick sort.The array is split into two arrays and then the remaining two arrays are sorted, so the loop is done until one element is left.Import Time,randomimport copydef Cal_time (func): #该装饰器用来测量函数运行的时间 def wrapper (*args,**kwargs): T1 = Tim E.time () r
