Assume that variables a, b, c, and d are mapped to registers $s0, $s1, $s2,

and $s3, respectively. Write a MIPS program that implements a = b * 2 +

c/4 + d%8 using only add, sub, addi, and, andi, or, ori, sll, and srl

instructions. Since b, c, and d must not be overwritten, use as many temporary

registers ($t0-$t9) as needed.
