XOR gate

The XOR gate (Exclusive OR) is a logic gate that outputs 1 (true) when exactly one of its inputs is 1 (true). That means that if both of its inputs are the same, the output will be 0 (false). The XOR gate does what is called an exclusive disjunction in logic.

INPUT		OUTPUT
A	B	A XOR B
0	0	0
0	1	1
1	0	1
1	1	0
