Problem 2 (30 pt) Add comments to the code and describe in one sentence what this code does. Assume that $a0 and $a1 are used for input and both initially contain the integers a and b, respectively. Assume that $vO is used for the output. Also, convert this MIPS code to add $tO, $zero, $zero loop: beq $a1, $zero, finish add $tO, $tO, $a0 addi $a1, $a1,-1 j loop finish: addi $tO, $t0, 100 add $vO, $tO, $zero
