    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))

    # Python 3 so it could be accepted!

# Enter your code here. Read input from STDIN. Print output to STDOUT

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

for _ in range(N):
    command = input().split()    
    if command[0] == 'pop':
        try:
            s.pop()
        except KeyError:
            pass
    elif command[0] == 'remove':
        try:

        except KeyError:

    Code only can be run in python3. Will have wrong answer in Pypy3

    n=int(input()) s=set(map(int,input().split())) N=int(input()) for _ in range (N): command=input().split() if command[0]=="pop": s.pop() elif command[0]=="discard": s.discard(int(command[1])) elif command[0]=="remove": if int(command[1]) in s: s.remove(int(command[1]))

    print (sum(s))
