    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)

    from collections import Counter

    No_Shoes = int(input())

    shoe = Counter(list(map(int,input().split())))

    No_Customers = int(input())

    Tsum=0

    for i in range(No_Customers):

    Customer = [int(i) for i in input().split()]

if Customer[0] in shoe.keys() and shoe[Customer[0]] > 0 :
    Tsum+=Customer[1]
    shoe[Customer[0]]-=1

    print(Tsum)

    X=int(input())
    S=list(map(int,input().split())) N=int(input()) li=[] for i in range(N): SP=[int(n) for n in input().split()] li.append(SP) summ=0 for i in li: if(i[0] in S): summ += i[1] S.remove(i[0]) print(summ)
