Draw a digital circuit $($using only$\_$decoder, OR gates and encoder$)$ that receive $3$ bit number XX$,$ X$,$ and output $2$ bit number Y$,$ Yo where Y$,$ Y$,$ equal the number of zeros in X$-$X$,\backslash$times for example if X$,$X$,$X$,=111$ then Y$,$ Y $=00$and if XX$,$X$,=100$ then Y$,$ Y$.=10$
