$[$Q$4]$ MinMax$2$ is a component with $2$ inputs $-$ A and B$,$ and $2-$outputs $-$ Max and Min. You guessed it$,$ you connect the $2n-$bit numbers at the inputs and the component drives the Max output with the bigger of the two and the Min output with the smaller of the two.

Your job is to design a component $-$ MinMax$4,$ with $4$ inputs and $4$ outputs which sorts the $4$ numbers using only MinMax$2$ components. Try to use as little as possible MinMax$2$ components.

Then try for MinMax$6$ using minimum number of MinMax$2$ and MinMax$4.$
