复制代码 代码如下:

from sys import argv

script, start, end = argv

vis = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

ans = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

def dfs(cur, m):

ans[cur] = m

if cur == int(end) - int(start) + 1:

for i in xrange(int(start), int(end) + 1):

print ans[i],

print

return

cur = cur + 1

for i in xrange(int(start), int(end) + 1):

if vis[i] == False:

vis[i] = True

dfs(cur, i)

vis[i] = False

for i in xrange(1, len(vis)):

vis[i] = False

dfs(0, start)
