collections.Counter()

    Why all test cases are not getting passed, can anyone shed some light on my mistake.

    from collections import Counter

x = int(input())
s = list(map(int,input().split()))
n = int(input())
c = set()

for i in range(0, n):
    j = list(map(int,input().split()))
    c.add(tuple(j))

c = list(c)
for i in range(0,len(c)):
    c[i] = list(c[i])
    
d = dict(Counter(s))

su = 0

for i in range(0,len(c)):
    if c[i][0] in d.keys() and d[c[i][0]]>0:
        d[c[i][0]] -= 1
        su = su + c[i][1]     

print(su)
