"""
A XOR Gate is a logic gate in boolean algebra which results to 1 (True) if only one of
the two inputs is 1, and 0 (False) if an even number of inputs are 1.
Following is the truth table of a XOR Gate:
------------------------------
| Input 1 | Input 2 | Output |
------------------------------
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
------------------------------
