meaning of xor

The two values that participate in the operation, if the two corresponding bit bits are the same, the result is 0, otherwise 1.That0^0 = 0,1^0 = 1,0^1 = 1,1^1 = 03 Features of bitwise XOR:(1) 0^0=0,0^1=1 0 xor or any number = any number(2) 1^0=1,1^1=

You are notGivenNnon-negative integers x0, x1,..., xn-1 Less than2 , but they does exist, and their values never change.I ' ll gradually provide you some facts about them, and ask you some questions.There is kinds of facts, plus one kind of question:

A number that appears only once in an array In an array of integers, except for two digits, the other numbers appear two times. Please write the program to find the two only occurrences of the number. Method One: The classical XOR technique uses

Basic knowledge: 1. And (&) Operations (bitwise AND)The and operation is usually used for bitwise operations. For example, the result of a number and 1 is the last bit of the binary. This can be used to judge the parity of an integer. the last bit

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,

due to contact with the lower level of data processing to the following use of finishing (reference network)bit arithmeticThe Operation component of a bitwise operation can only be integer or character data, and the bitwise operation considers the
