    this challenge is buggy, you don't need the first and third input to solve it.

    Here is Python 3 solution from my HackerrankPractice repository:

    _, a = input(), set(input().split())
_, b = input(), set(input().split())
print(len(a.union(b)))

    Feel free to ask if you have any questions :)

    Simple solution in Python:

    n = input()
set_n = set(map(int, input().split()))
b = input()
set_b = set(map(int, input().split()))
print(len(set_n.union(set_b)))

    n_english = int(input())
zb_eng = set(map(int, input().split()))
n_french = int(input())
zb_fre = set(map(int, input().split()))

a = zb_eng.union(zb_fre)
print(len(a))
