    without counters... coz i think there is no need to use it here

    n = input()
boots = map(int, raw_input().split())
orders = [map(int, raw_input().split()) for _ in range(input())]
result = 0
for i in orders:
    if i[0] in boots:
        result += i[1]
        boots.remove(i[0])
print result
