    A oneliner:

    n, m = map(int, input().split())
arr = list(map(int, input().split()))
arr_a = set(map(int, input().split()))
arr_b = set(map(int, input().split()))

print(sum(1 if e in arr_a else -1 if e in arr_b else 0 for e in arr))

    n,m=list(map(int,input().split()))
arr=list(map(int,input().split()))
A,B=set(map(int,input().split())),set(map(int,input().split()))
a,b=[x for x in arr if x in A],[x for x in arr if x in B]
print(len(a)-len(b))

    x = list(map(int, input().split())) my_set = list(map(int, input().split())) set_A = list(map(int, input().split())) set_B = list(map(int, input().split())) score = 0

    for i in my_set: if i in set_A: score += 1 if i in set_B: score -= 1

    print(score)

    the time limit is exceeding, any help with that

    using a dictionary 

    happiness = 0

n, m = input().split()  # not used
arry = input().split()
A = set(input().split())
B = set(input().split())

d = {}
for num in arry:
    if num not in d:
        d[num] = 1
    else:
        d[num] += 1

for num, occurrences in d.items():
    if num in A:
        happiness += occurrences
    elif num in B:
        happiness -= occurrences

print(happiness)
