This unit has a 2-bit control lines P[1:0] to select the required
operation, a 4-bit input data D[3:0], and a 4-bit register output
Q[3:0]. Note: do not use any adder in the design.

b. Write the verilog code for this circuit. You do not need to
simulate this circuit, but you have to make sure it is free from
syntax errors. Use the template below as a starting point.
module alu4 (input clk, input [1:0] P, input [3:0] D, output reg
[3:0] Q);
// declare internal wires if needed
// here is your design
always @(posedge clk)
