本文共 276 字,大约阅读时间需要 1 分钟。

运算规则:0^0=0; 0^1=1; 1^0=1; 1^1=0;

即:同0异1

例如:3^5 = 0000 0011 | 0000 0101 =0000 0110,因此,3^5 = 6


基本性质:

1、交换律 a^ b = b^a

2、结合律 (a ^ b)^ c = a^ (b^c)

3、对于任何数x,都有 x^ x=0,x^0=x (异或自身等于0,异或0等于自身)

4、自反性 A ^ B ^ B = A ^ 0 = A

5、IF a ^ b = c THEN b ^ c = a

6、0和1 ^ 1 都和自身相反; 0和1 ^ 0都和自身相同
