给你一个整数组成的列表L，按照下列条件输出：若L是升序排列的,则输出"UP";若L是降序排列的,则输出"DOWN";
若L无序，则输出"WRONG"。
from __future__ import print_functionL = [6,5,4,3,2,1]eum = {'1':'UP','2':'DOWN','3':'WRONG'}def is_up_or_down(L):    temp = L[0]    ret = 0    for item in L:        if item > temp:            ret = ret | 1        elif item < temp:            ret = ret | 2        temp = item    return eum[str(ret)]print(is_up_or_down(L),end='')
