下面的Python代码用于输出每个数对应的质因数列表，输出形如： {5: [5], 6: [2, 3], 7: [7], 8: [2,2, 2]} 。 (    )

n, m = map(int,input().split())
if n > m:
	n, m = m, n
prime_factor = {} #保存每个数的质因数
for i in range(n, m + 1):
	j, k = 2, i
	while k != 1:
		if k % j == 0:
			prime_factor[i] = prime_factor.get(i,[]) + j
			k //= j
			continue
		j += 1
print(prime_factor)
