from itertools import permutations

S, k = input().split()

A = sorted(list(permutations(S, int(k))))

for i in range(len(A)):
    print(
        ''.join(A[i])
    )

두 번째 시도

from itertools import permutations

S, k = input().split()

li_s= sorted(list(S))

for i in list(permutations(li_s, int(k))):
    print(''.join(i))
