    For Python3 Platform

    n_A = int(input())
A = set(map(int, input().split()))
N = int(input())
for _ in range(N):
    cmd, len = input().split()
    B = set(map(int, input().split()))
    
    if(cmd == "intersection_update"):
        A.intersection_update(B)
    elif(cmd == "update"):
        A |= B
    elif(cmd == "difference_update"):
        A.difference_update(B)
    elif(cmd == "symmetric_difference_update"):
        A ^= B

print(sum(A))
