蓝桥杯算法训练VIP-集合运算

解题思路:

注意事项:

参考代码:

n = int(input())

L1 = list(map(int,input().split()))

L1.sort()

m = int(input())

L2 = list(map(int,input().split()))

L2.sort()

for i in L1:

    if i in L2:

        print(i,end=' ')

print()

L3 = sorted(list(set(L1+L2)))

for i in L3:

    print(i,end=' ')

print()

for i in L1:

    if i not in L2:

        print(i,end=' ')
