xor operation

Encrypt a string using the "^" XOR operation Idea: 1. First create a string input scanner; 2. Via char[] array = Password.tochararray ();//get the character array; 3. Iterate through the character array and use the traversal as it is currently

A binary-based bitwise operation, denoted by the symbol XOR or ^,The algorithm is for each bits of the operator's sides, the same value takes 0, and the value is 1.It differs from Boolean operations in that when both sides of the operator are 1

bit arithmeticThe operation component of a bitwise operation can only be integer or character data, and the bitwise operation considers the operand as a bit string information composed of binary bits, and completes the specified operation by bit,

Maybe a lot of beginners like me have never seen this symbol ^This is a different or operational symbol, OK, now we're going to start analyzing how it works!Knowledge of XOR operation click on this link to

This article describes an Easy-to-use encryption/decryption algorithm that uses XOR or XOR operations. This algorithm is simple in principle and aims to make readers have a more intuitive impression on the encryption/decryption of information. 　　

Self-lazy, look at the feeling of the reliable XOR operation: 1 ^ 1 = 0 1 ^ 0 = 1 0 ^ 1 = 1 0 ^ 0 = 0 The ASCII encoding of the character ' A ' is 65:00000000 01000001 Take integers 7:00000000 00000000 00000000 00000111 After XOR operation: 00000000

Test instructions: Allows you to construct a sequence that makes the sequence XOR and maximum, the sequence is full of n, and the sequence and calculation method is SUM = A[1] ^ 0 + a[2] ^ 1 + a[3] ^ 2 + ... a[n] ^ nFeelings: Before did not do the

Two values that participate in the operation, if two corresponding bit bits are the same, the result is 0, otherwise 1Char a1 = ' Ten ', a2 = ' point ', a3 = ' Enter ', A4 = ' attack ';Char secret = ' 8 ';A1 = (char) (A1 ^ secret);A2 = (char) (a2 ^

Test instructions: Given an n (1 Enumerate all the numbers from N ~ 0, for each number to find it xor or to get the binary to be 1 of the number or 1 as many as possible.For each number, first find the same number of bits as it is 1, and then take

Make good use of the different or can produce wonderful effects.The nature of an XOR operation:no matter what a number different or it itself equals 0 . Other words. Assuming we are different from beginning to end or each number in the array, then
