given a list of M numbers and a positive integer N, print the sum of numbers whose position in the list is divisible by N. consider that the positions of numbers range from 1 to N.
Explanation : Given N = 1, M= 7 and the numbers_list = [4, 8, 6, 6, 7, 9,3]
as every position is divisible by 1, 4+8+6+6+7+9+3=43
so, output is 43
Input : 1 7
4 8 6 6 7 9 3
Output : 43
Input : 4 13
7 3 10 4 5 8 4 9 6 9 10 1 4
Output : 14
N_M_lst = list(input().split())
N = int(N_M_lst[0])
M = int(N_M_lst[1])
number_lst = list(input().split())
number_lst = [int(i) for i in number_lst]
sum = 0
for i, item in enumerate(number_lst, 1):
if i % N == 0:
sum += item
print(sum)
