OutputI0O7SJstart with a string array to sort it out, decisively super memory. Analyze the strings given:07jsoi-->07+......+i7jsoi0-->7+......+0I07jso-->i07+......+ojsoi07-->jsoi07+ (7)Oi07js-->oi07+......+sSoi07j-->soi07+jyou can see that 07,7,i07,jsoi07,oi07,soi07 is all the suffixes of the original string, so we only need to sort these suffixes when sorting. This will use the suffix array. Note: Because it is annular, it is necessary to first copy the multiplication string, get the new strin

Surprisingly it is isn't a public Key cryptosystem, but their encoding and decoding are based on the secret keys. They chose the secret key at their's last meeting into Philadelphia on February 16th, 1996. They chose

This article introduces two methods of cipher encryption, these two are very common can be found at random Baidu. 1. Morse Code; Say password encryption has to be put to the method. It's a classic. First of all, tell him the comparison table, directly above the picture. The core idea is to replace the plaintext cipher and replace the characters with the. two symbols; 2, fence password; The so-

In cryptography, Caesar's code (or Caesar's encryption, Caesar's transformation) is one of the simplest and most widely known cryptographic techniques. It is a technique for replacing encryption, in which all letters in plaintext are replaced by a fixed number of Cheng Mi-wen (or forward) after the alphabet is offset. For example, when the offset is 3, all the letters A will be replaced with D,B into E, and so on. This method of encryption was named after Caesar, who had used this method to comm

Originally wanted to be poor to lift all passwords, the algorithm is either nested too deep, or special consumption of memory (will overflow). Later, a simple algorithm with very low repetition probability was chosen. The code is as follows: Copy

Here are four PHP generated random password functions Oh, simple and practical method is a user-defined encryption function, so if you do not know your encryption algorithm is difficult to crack. Here are four php tutorials to generate random

There is an encryption method, which first gives the arrangement of N numbers, then input a string with a string length For example, 4 5 3 7 2 8 1 6 10 9, Hello Bob, then each character in the string corresponds to a number from left to right: 4 5 3

This question is not so difficult. First, my thoughts were we shoshould use a lot of code to find out the loop block, but there is no need to do that. You just need to get every new position of char in the string. Algorithm is also easy, just like

Method One: 1. Generate a random integer, such as 35, in 33–126 2, convert 35 to the corresponding ASCII code characters, such as 35 corresponding # 3, repeat the above 1, 2 steps n times, connected to the N-bit password The algorithm mainly
