There is XOR function in Java - a^b
Java中有XOR函数 - a ^ b
For exemple: 5^3 = 6
例如：5 ^ 3 = 6
Can you tell me inverse function? If I have 6 and 3 can i get range of numbers which include number 5?
你能告诉我反函数吗？如果我有6和3可以获得包括数字5的数字范围？

The inverse is XOR!
逆是异或！
If you have:
如果你有：
c = a^b;
You can get a or b back if you have the other value available:
如果您有其他可用值，您可以获得a或b返回：
a = c^b; // or b^c (order is not important)
b = c^a; // or a^c
For example if a = 5, b = 3 (and thus c = 6 as you mentioned) you get:
例如，如果a = 5，b = 3（因此你提到的c = 6），你得到：
b=0011 (3) a=0101 (5)
c=0110 (6) XOR or c=0110 (6) XOR
---------- ----------
a=0101 (5) b=0011 (3)
