The posting bad character algorithm (Bad-character) and the Good suffix Algorithm (good-suffix), which are recommended above, are used to determine how many bits to move (shift) or move, not to elaborate here.

1 PrefaceAt present, most of the commercial software and shareware are licensed by the registration code to ensure that the software itself is not stolen, in order to ensure its own interests. Although some versions of many commonly used software systems have been cracked by others, the way in which the registration code is licensed is an effective means of protecting the software system itself, for softwar

This article, in addition to the code is written by itself, the rest is already existing content. The author just finishing inductive study, certainly not original, but is not the translation, is not reproduced, so can only be labeled as original, because the code is original. Salute to the Elder!first, the basic conceptsorting algorithm (sorting

Exploring the principle and programming implementation of the SHA-1 algorithm in Redis source codeGuide The SHA-1 algorithm is short for the first generation of "Security Hash algorithm", and is essentially a Hash algorithm. SHA standards are mainly used for digital signatures to generate message digests, which were on

Quick sort, short-line, often called quicksort, QSort. It is very common in the sorting algorithm, its programming complexity is low, the time complexity O (LOGN), the Space Complexity O (N), the execution efficiency is stable, and the constant is very low.The basic idea is two points, for example you want to sort N the number, you call the Qsort (1,n). So the quick line will do this:1. Find a number X2, the n number is divided into two parts, the lef

In fact, supposedly, the algorithm should say what greedy, search, DP, two points of the basic

It is a typical NP-complete issue. before defining the satisfied question SA

First, it refers to the string SEARCH, that is, to find the position where A specified string B appears in A specified string A, or to count the number of times other B appears in.　　①MS provides a strstr function prototype: extern char * strstr (char * str1, char * str2); header file View Code char * __cdecl strstr (const char * str1,const char * str2 ){char *cp = (char *) str1;char *s1, *s2;if ( !*str2 )return((char *)str1);while (*cp)

Improvement of KMP algorithmThe KMP algorithm has some improved versions to speed up lookups, and can generally speed up the matching process with some information in the S string.For example, if S = "Aaaaaaaafaaaaaaaaaaaab", T = "Aaaaaaab".During the lookup process, the "F" in

RC4 Encryption AlgorithmRC4 encryption algorithm is the number one in the famous RSA trio Ron Rivest designed a variable-length stream encryption algorithm cluster in 1987. It is called a cluster, because its core part of the S-box length can be arbitrary, but generally 256 bytes. The speed of the algorithm can reach about 10 times times of DES encryption, and it

that runs, swapping is almost as bad as bubbling. This is true indeed. The number of cycles is also 1/2* (n-1) *n, so the complexity of the algorithm is still O (n*n). Since we cannot give all the information, we can only tell you that they are equally bad in exchange (in some cases slightly better, in some cases slightly worse). p# subtitle #e# 3. Choice of law: Now we can finally see a little hope: Selection method, this method improves a bit of

Following the first two sections, we discuss the coding of polarization codes and the Gaussian approximation method in the Gaussian channel, then we focus on a very important algorithm of polarization code construction. This algorithm does not have a definite noun, so we named it the "Tal-vardy algorithm " with the nam
