    For Python3 Platform

    n = int(input()) s = set(map(int, input().split())) N = int(input())

    for _ in range(N): cmd = input().split()

    if(cmd[0] == "pop"):
    try:
        s.pop()
    except KeyError:
        pass
elif(cmd[0] == "remove"):
    try:
        s.remove(int(cmd[1]))
    except KeyError:
        pass
elif(cmd[0] == "discard"):
    s.discard(int(cmd[1]))

    print(sum(s))
