Write a function @leading_hand(h, m)@ that given integers and representing a digital hour returns the leading hand of an analogical watch pointing out that hour. Depending on value parameters the function returns either the string "hour hand", "minute hand" or "draw". Leading hand is the one closest to following the clockwise rotation. We assume hour hand has only possible configurations and minute hand has .
>>> leading_hand(22, 51) 'minute hand' >>> leading_hand(21, 45) 'draw' >>> leading_hand(6, 28) 'hour hand' >>> leading_hand(4, 20) 'draw'
