how to calculate xor

I think the XOR thing is particularly magical, and the most amazing thing is this nature. A XOR B xor b=aSo you don't have to worry about repeating things.On the question of XOR you can go to the MO team's "Gaussian elimination of the Xor Equation

Bitwise -AND Operator (&) Participate in the operation of the two data, 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 For example: 3&5

Bitwise AND Operator (&) To participate in the operation of the two data, press bits for the "and" operation. Operation Rules:0&0=0;   0&1=0;    1&0=0; 1&1=1; That is: two digits at the same time "1", the result is "1", otherwise 0 For example: 3&5
