67. Decoder

How do you plan to solve it?

module decoder3to8(s,y);
input [2:0] s;
output [7:0] y;
assign y[0] = ~s[2] & ~s[1] & ~s[0];
assign y[1] = ~s[2] & ~s[1] & s[0];
assign y[2] = ~s[2] & s[1] & ~s[0];
assign y[3] = ~s[2] & s[1] & s[0];
assign y[4] = s[2] & ~s[1] & ~s[0];
assign y[5] = s[2] & ~s[1] & s[0];
assign y[6] = s[2] & s[1] & ~s[0];
assign y[7] = s[2] & s[1] & s[0];
