exclusive or operation

C # The supported bitwise logical operators are shown in Table 2.9. Operator number Meaning Calculation object type Calculation Result type Number of Objects Instance ~ Bit LogicNonOperation

In C #, you can perform logical operations on integer computing objects by bit. The meaning of logical operations by bit is that each bit of the object to be operated is obtained in sequence for logical operations. The logical operation result of

I have prepared to write a string series of interview questions for a long time. I have already written about a dozen questions, but I found that the article is so long that I have no patience to read it myself, simply split it into several series,

Use an exclusive OR operator to encrypt integers.I. What is the operator: Binary ^ operators are predefined for integer and bool types. For an integer, ^ returns the bitwise XOR of the calculated operand ". For the bool operand, the logic of the ^

LeetCode exercise-singleNumber Question meaning: In a numeric array, most numeric values appear twice, and only one numeric value appears once.Required. The time complexity is linear, and the space complexity is O (1 ). Solution: 1. sort and search.

Use the XOR algorithm to share data in the PHPMySQL application. The XOR algorithm principle is based on the encryption method. the location change method is too simple, especially when the amount of data is small, it is easy to guess the plaintext

This article introduces an easy-to-use encryption and decryption algorithm: using an exclusive or (XOR) operation. This algorithm is simple in principle and aims to give readers a more intuitive impression on the encryption and decryption of

Text/figure DecemberOnline worms are used to running QQ, MSN, FlashGet, and other programs every day. Do you think it is troublesome to repeat the same action day after day? Therefore, using a program to enable multiple processors is definitely a

1. Bit logical non-operation Bit logical non-operation is a single purpose and only one operation object. Bitwise logical non-operation performs non-operation on the value of the computing object by bitwise. That is, if a bit is equal to 0, it is

24-bit BMP bitmap file To use BMP bitmap for encryption, you must first understand the storage format of BMP files. The 24-bit true-color BMP bitmap file consists of three Part: The first part is the BMP file header. The first two bytes are "BM" and

1.1.1 Summary   Recently, network security has become a focus. In addition to domestic plaintext password security events, there is also a major impact-Hash Collision DoS (Denial-of-service attacks through Hash collisions ), some malicious people

[Topic] All numbers except two in an integer array appear twice. Find the numbers that appear only once in the array. Time complexity O (N) and space complexity O (1) are required ).   [Thinking path] First, let's consider a simple case: if

I was planning to write this article when I came back from work. On the one hand, it is a note record for today's learning, and on the other hand, it is a basic knowledge of SWF file encryption for some friends. The reason is that it is the

There are many introductions on the DES algorithm on the Internet, with the same general idea. However, the handling of many details is not clear, and the source code quality is also uneven. For this reason, I have spent a lot of time studying it.
