xor operation

QR Code, also known as the CODE,QR Universal Quick Response, is a mobile device in recent years a hyper-popular encoding method, it can save more information than the traditional bar code barcode, but also can represent more data types: characters,

Today, when doing a problem, suddenly appeared a problem, is not the use of intermediate variables, the value of two shaping variables to swap, began a bit of a Meng, how to change? Later or with two variables constantly do plus and minus

Encryption principle:1, through the key scheduling algorithm KSA initialization state vector s (S is a random number generator, called S-box)2, and then the pseudo-random number generation algorithm Prga to get the key stream keystream3, the key

136. Single numberGiven an array of integers, every element appears twice except for one. Find the single one. (easy)Note:Your algorithm should has a linear runtime complexity. Could you implement it without using extra memory?Analysis:The first

This paper uses the ListBox self-painting to achieve two special effects (see figure), the left side of the style is their own sudden inspiration to think of, the right side of the style from the " C + + Builder research " a post, the old demon with

1. Bitwise operation"and" Operations: two data to participate in the operation, press bits for "and" operation.    Arithmetic Rules:0&0=0;    0&1=0;     1&0=0; 1&1=1;That is , the two-bit is "1" at the same time, the result is "1", otherwise 0"or"

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

We know that the perceptron is the simplest neural network, with only one layer. Perceptron is a machine that simulates the behavior of biological neurons. So this time to teach you how to use Python to implement the Perceptron, the model is as

The recent testing process has encountered a case of system AES and FEC, here is a brief introduction to their principles and applications in the Gpon system.Aesfor the gpon system, the downlink data is sent by broadcast to all ONU, involving a

Now basically do not communicate with the hardware, software development very few people to understand these logical operators, often use some logical operators, today to tidy up, a common understanding of the various operators how the

Interview question 40: two numbers in an array that occur only onceSubmission URL: http://www.nowcoder.com/practice/e02fdb54d7524710a7d664d082bb7811?tpId=13&tqId=11193or http://ac.jobdu.com/problem.php?pid=1351title: in an integer array, except for

The symbol of XOR is ^. Bitwise XOR, the equivalent long Binary mode performs a bitwise XOR OR operation on each bit of a bitwise or binary number. The result of the operation is that if a bit is different then the bit is 1, otherwise the bit is the
