**************** Problem 16
       beq    $zero,$zero,LABa    # 4 instructions after next
       addi   $v0,$zero,0
LABb   lw     $t0,0($a0)
       add    $v0,$v0,$t0
       addi   $a1,$a1,-1
LABa   bgtz   $a1,LABb            # 4 instructions before next
       addi   $a0,$a0,4
       jr     $gp


Program was inteded to add the elements of an array passed in $a0 of size $a1
However, there is a problem with the return!

It is *very* important to figure out where the branches goto!
