collections.Counter()

    Well, I didn't use Counter()... this seemed pretty easy without it

    # Enter your code here. Read input from STDIN. Print output to STDOUT
# from collections import Counter
no_of_shoes=int(input())
size_stocks=list(map(int, input().split(" ")))
customers_count=int(input())
request_size_bid=[]
for i in range(customers_count):
    x,y=input().split(" ")
    request_size_bid.append((int(x),int(y)))

profit=0
for i in request_size_bid:
    if i[0] in size_stocks:
        profit+=i[1]
        size_stocks.remove(i[0])
print(profit)
