# Summing Program

The loop is already correct for the problem. Don't change it. Computing the sum is done by adding just two statements:

    ##
    ##  Sum of integers 0 .. 9
    ##
    ## Registers:
    ##  $8  --- loop control
    ##  $9  --- scratch
    ## $10  --- sum

    init:   ori    $10,$0,0       # sum = 0
            ori    $8,$0,0        # count = 0
    test:   sltiu  $9,$8,10       # count < 10
            beq    $9,$0,endLp    # end loop if count >= 10
            sll    $0,$0,0        # delay

            addu   $10,$10,$8     # sum += count

            addiu  $8,$8,1        # count++ ;
            j      test
            sll    $0,$0,0        # delay

    endLp:  sll    $0,$0,0        # jump target

### QUESTION 13:

Of all the `sll`s in the program, which one is the most dangerous to remove?
