(Exercise) Create first 1posv1.s Start from first1pos.v to do the following procedure. Given a value in sao, returns in svo the position of the leftmost bit in the word in sao. If sao contains 0, store -1 in svo. You are allowed to modify sao in the process of finding this position. Positions range from 0 (the rightmost bit) to 31 (the sign bit). This version should repeatedly shift left sao, checking the sign bit at each shift. Work it out on paper if you are not sure how this works with a few sample numbers
