SPOJ - Problem DQUERY

Hello , can someone please help me out in this problem ?
I am getting runtime error(sigsegv) while submitting. I tried changing array sizes but not working.

Here is my code

Thank you

N = int(input())
arr = [int(i) for i in input().split()]
for _ in range(int(input())):
	min_,max_ = map(int , input().split())
	print(len(set(arr[min_ - 1:max_])))

i think this should work

Hey , i couldn’t understand this as i don’t know python. Can you please just write what part should i modify ?
