xor operation

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

1: XOR operation: The symbol ^, also known as the XOR operation, its rule is if the operation of the two binary numbers, the result is 0, the XOR is 1, namely: 0^0=0; 0^1=1; 1^0=1;1^1=0　　2: Performs a bitwise XOR on two

In CFB mode, the previous ciphertext packet is sent back to the input of the cryptographic algorithm. The so-called feedback, which refers to the meaning of the return input, as shown:In the ECB mode and CBC mode, the plaintext packet is encrypted

1. With intermediate volume switchingUsually we do it (especially at the Learning stage): Define a new variable and use it to complete the exchange. The code is as follows:int x = tenint y =int temp ==This algorithm is easy to understand, especially

First look at the possible values: 123456789101112131415 cmblackness = blackness; cmdstinvert = Dstinvert; cmmergecopy = mergecopy; cmmergepaint = mergepaint; cmnotsrccopy = notsrccopy; cmnotsrcerase = notsrcerase;

Leetcode problem solving a single number original questionIn an array, except for one number, the rest of the numbers appear two times to find the number that appears only once.Note the point: The algorithm time-to-clutter requirement is O (
