"""
A NOR Gate is a logic gate in boolean algebra which results to false(0)
if any of the input is 1, and True(1) if both the inputs are 0.
Following is the truth table of a NOR Gate:
| Input 1 | Input 2 | Output |
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 0 |
Following is the code implementation of the NOR Gate
