why there is problem with N

Question

def solution(N,A,M,B,X):

N=int(input("enter the array element"))
A=[]
n=0
for e in input().split():
if(n<N):
A.append(int (e))
n+=1
M=int(input())
n=0
B=[]
for e in input().split():
if(n<M):
B.append(int (e))
n+=1
X=int(input())
print(solution(N,A,M,B,X),end='')
