For an example:
Let's take 0010
We have to find 2's complement of this number.
So, first, we will find 1's complement.
Which will be: 1101
Now we will add '+1' with that 1's complement.
Therefore the answer will be: 1101+1=1110
This is the 2's complement of that number.
Thus we can find 2's complement of any given number.
