"""
A NAND Gate is a logic gate in boolean algebra which results to 0 (False) if both
the inputs are 1, and 1 (True) otherwise. It's similar to adding
a NOT gate along with an AND gate.
Following is the truth table of a NAND Gate:
------------------------------
| Input 1 | Input 2 | Output |
------------------------------
| 0 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
------------------------------
