Can you help me with the first question?

Activities Document Viewer Tue 21:43 1 of 2 148.73% CpE 442/CS455: HW2 2.29 Add comments to the MIPS code and describe what it computes. Sa0 & Sal are used for the input and both initially contain the integers a and b. Sv0 is used for the output. add $t0, $zero, $zero beq Sal, Szero, finish add $t0, St0, Sa0 sub Sal, Sal, 1 oop: loop finish addi $t0, St0, 100 add $vO, $t0, Szero 2.34 The following program tries to copy words from the address in register $a0 to the address in register Sal, counting the number of words copied in register Sv0. The program stops copying when it finds a word equal to 0 This terminating word should be copied but not counted. There are multiple bugs in this MIPS program; fix them and turn in a bug-free version addi Sv0, Szero, 0 //Initialize count
