Consider variables a, b, c, d and e are assigned to registers $s3, $s4, $s5, $s6 and $s7 respectively. Consider the base address of the arrays X and Y are in registers $s0 and $s1 respectively. Write an efficient MIPS assembly instruction which does the same function as the following MIPS instructions? sll $t0, $s3, 2 add $t0, $s0, $t0 sll $t1, $s4, 2 add $t1, $s1, $t1 lw $s3, 0($t0) addi $t2, $t0, 4 lw $t0, 0($t2) add $t0, $t0, $s3 sw $t0, 0($t1) Note: Efficient assembly instruction means minimize the number of instructions required to do the job.
