Can anyone explain the steps for the assembly language? especially the "sll" and "lw" part. Thanks! I will give a good rate.

2.4.1 [10] For the Cstatements above, what is the corresponding MIPS assembly code? 2.4.2 [5] For the C statements above, how many MIPS assembly instructions are needed to perform the C statement? 5 s0 s1 sa S3 sub $t0, $s3, $s4 #$t0-1-j | sll $t0, $t0, 2 #shift left 2 to *4 | add $to, $to, $s6 #addr of Ali-j] | $S4 s6 $ | sw $t1, 32($s7) #store 2 B[8]
