How do you plan to solve it?

/*Write your code here*/
module demux1to4(input d,input [1:0]s,output reg[3:0]y);
integer i; // loop variable must be declared (synthesizable)
    always @* begin
    y = 4'b0000;
    for (i=0 ; i<4; i = i +1)begin
        if(s == i)
           y[i] = d;
        else 
           y[i] = 1'b0;
    end
    end
