The following functions each determine all pairs of two values in alist that sum to asum. As is shown in the notes, (a) write the complexity class of each statement on its right, where N is len(alist). def how_sum_1 (alist, asum): def how_sum_2 (alist, asum): for f in alist: aset = set (alist)for s in alist: for v in alist: if f+s asun : if asum-v in aset return (f, s) return (v, asum-v) return None return None (lb) b)c)d) for both functions, which takes longer: finding a solution or finding no solution?
