exclusive or operation

Bitwise AND operator (&) The two data involved in the operation perform the "and" Operation in binary bits. Calculation rule: 0 & 0 = 0; 0 & 1 = 0;  1 & 0 = 0;   1 & 1 = 1;       That is, if the two digits are "1" at the same time, the result

1. Deep linked list First, we will introduce some common methods for linked lists: Append (x): adds an element to the end of the linked list. Extend (l): merges another linked list into this linked list. Insert (I, X): insert an element

This is the first State compression question I have made, and I have understood it myself and understood it thoroughly. A: A string consisting of several uppercase letters. Then, select as many strings as possible to make these letters appear

The leetcode has the following two single number problems: 1. Assume that all elements in an integer array appearTwoOnly one element appears once. Find the element that appears once. 2. Assume that all the elements in an integer array appear3.Only

I. Data Transmission instructions ── ─ They transmit data between the storage and registers, registers, and input and output ports. 1. General Data Transmission commands. MoV transfer word or byte. For example: mov eax, 11 meaning: eax = 11 Movsx

IVideo Encoding 1.1 target of video compression and encoding 1) Ensure compression ratio 2) Ensure recovery quality 3) easy to implement, low cost, and reliability   1.2 starting point of compression (feasibility) 1) Time Correlation In a video

The weekly test was abused. after a long time of game questions, I found a lot of information about the game. I felt like I was still moving a little bit. Before going to bed, I would like to give a brief summary. I hope I can feel something later !!

Question: The minimum integer in an array that is at least startno and does not exist in an unordered integer. For example, the minimum integer not less than 3 in, is 3.   The following test code shows that the implementation is not

Getting started-Chapter 1-Preface Many of my friends said they didn't quite understand the tutorials and the books of the boss. So I try to make it the easiest to understand. I wrote this article to my friends who are just getting started and not

When I read a book today, I see: "The characteristics of the exclusive or operation are: if a ^ B = C, then C ^ B = A and C ^ A = B. This rule can be used ." I plan to give it a try. I first assume that there is a key and then the number is given.

Compiler stack protection technology in GCC Buffer overflow, represented by stack overflow, has become the most common security vulnerability. Security problems are common. As early as 1988, Morris, a graduate student in the Computer Science

Key words: CRC algorithm principle; CRC verification; modulo 2 (mod 2); mod 2The CRC verification algorithm adopts a binary algorithm called "modulo 2 operation. The modulo 2 operation is the core part of the CRC operation. Therefore, before

  There is a very interesting game, that is, there are several heaps of objects, either matchsticks or pawn pieces. TwoPeople take several objects from the heap in turn, and the final winner of the light object is required. This is an ancient game
