 Assume that register $12 contains an unsigned integer X. a) Show how X/4 (i.e., X divided by 4) can be computed and placed into register $10 using no more than two instructions, both of which are logical shift instructions.

b) Show how  X MOD 4 (i.e., X modulo 4) can be computed and placed into register $10 using no more than two instructions, both of which are logical shift instructions.

c) If instead register $12 contains the 32-bit IEEE 754 floating point negative number -3.56E-4, what floating point value would register $10 contain after the following instructions are executed?

                       lui       $10,0xFF80

                       xor      $10,$10,$12
