    Here's my solution to this problem:-

    from collections import Counter shoes=int(input()) shoe_size=list(map(int,input().split())) counter=Counter(shoe_size) customers=int(input()) lst=[] for i in range(1,customers+1): customer_info,price=map(int,input().split()) if counter[customer_info]>0: counter[customer_info]-=1 lst.append(price) else: pass print(sum(lst))

    import collections as c

x = int(input())
available_sizes= input()
no_of_customers= int(input())

cutomer_and_shoe_price_list= []

for cutomer_shoe_price in range(no_of_customers):
    cutomer_and_shoe_price = input()
    cutomer_and_shoe_price_list.append(cutomer_and_shoe_price.split(" "))

available_sizes_list= [i for i in available_sizes.split(" ")]
# print(available_sizes_list)
available_sizes_list_count= c.Counter(available_sizes_list)
# print(available_sizes_list_count)  # Counter({'5': 2, '6': 2, '2': 1, '3': 1, '4': 1, '8': 1, '7': 1, '18': 1})

# print(cutomer_and_shoe_price_list) # [['6', '55'], ['6', '45'], ['6', '55'], ['4', '40'], ['18', '60'], ['10', '50']]
 

price_list= []

for keys, values in available_sizes_list_count.items():
    for i in cutomer_and_shoe_price_list:
        if i[0] == keys:
            values= values - 1
            price_list.append(i[1])
            if values == 0:     # Prevents overselling
                break
            
    # print(keys, values)
print(sum(list(map(int, price_list))))
