2. Translate the following code to MIPS assembly. Use only ADD, SUB, LW, and SW instructions. Starting addresses of arrays a, b, and c are stored in registers $s1, $s2 and $s3, respectively. You can use temporary registers $t1-$t9 to store intermediate values. Add comments to your code to explain the code. (Points 35) c[3] = a[2] + b[21]
