注意事项:

参考代码:

def to(a):
    ls=[i for i in str(a)]
    ls.sort()
    return ls 
def isgu(ls):
    lis=[]
    for i in range(len(ls)):
        for j in ls[:i]+ls[i+1:]:
            if ls[i] in lis:
                continue
            else:
                if to(ls[i])==to(j):
                    lis.append(ls[i]) 
                    lis.append(j)
                    break
    lt=[]
    for i in ls:
        if i not in lis:
            lt.append(i)
    lt.sort()
    return  lt
while True:
    n=int(input())
    if n==0:
        break
    ls=list(map(int,input().split()))
    if len(isgu(ls))==0:
        print('None')
    else:
        for i in isgu(ls):
            print(i,end=' ')
        print()
