Design a $4-$bit comparator that has a cascading property such that by connecting the output of a higher stage to the inputs of a lower stage you can have an $8-$bit or $12-$bit or higher comparator.

The figure below shows how three $4-$bit comparators are cascaded to compare two $12-$bit numbers $($X$11...$ X$0)$ and $($Y$11...$ Y$0).$ The most significant $4-$bits are connected to the left comparator while the least significant bits to right comparator

Modify the comparator explained in the lecture slides such that it will have $3$ more inputs
