Enter your code here. Read input from STDIN. Print output to STDOUT

Read a single line of input for n and m

nm = input() # Example input: "3 2"

Split the input line into parts and convert each to an integer

n,m = map(int, nm.split())

array = list(map(int, input().split()))

2sets: A: set, B:set each containing m integers

A = set(map(int, input().split())) B = set(map(int, input().split()))

happiness = 0

for i in array: if i in A: happiness+=1 elif i in B: happiness -=1 else: happiness +=0 print(happiness)
