$31.$

Design a combinational circuit with three inputs and one output.

$(1)221,0$

A circuit in which the output is $1$ when the input binary value is greater than $2,$ and $0$ in other cases.

$(2)231,0$

A circuit in which the output is $1$ when the input binary value is not divisible by $3.$ and $0$ in other cases.

$(3)101,0($ e$.$g$.010-->0,110-->1)$

A circuit in which the output is $1$ when there are more $0$ s than $1$ s in the input, and $0$ in all other cases. $($ e$.$g$.010-->0,110-1$
