Write a procedure that multiplies any unsigned 32-bit integer by EAX by using only shifting and addition. Pass the integer to the procedure in the EBX register and return the product in the EAX register. Write a short test program as well that calls the procedure and displays the product. You may presume the product of the multiplication never gets larger than a 32-bit representation.
