    I didnt use collections Counter

    from collections import Counter
num_shoes = int(input())
shoe_sizes = list(map(int, input().split()))
num_customers = int(input())
customer_info = list()

for i in range(num_customers):
    customer_info.append(list(map(int, input().split())))

total = 0
for i in range(num_customers):
        if customer_info[i][0] in shoe_sizes:
            total = total + int(customer_info[i][1])
            shoe_sizes.remove(customer_info[i][0])
print(total)
