Write a subtoutine in MARIE assembly that multiplies two values where the arguments for this subroutine are two pointers (each pointer pointing to a value). The routube, multiply (a,b), performs *a x *b where a's value is the address storing the value being multiplied (*a uses a's contents to retrieve the value being multiplied), and b's value is the address storing the value being multiplied (*b uses b's contents to retrieve the value being multiplied).
