Code Python :

import math
N = int(input())
if N < 1 or N >= 2 * 10**9:
    print("-1")
    exit()
dem = 0
for i in range(1, int(math.sqrt(N)) + 1):
    if N % i == 0:
        dem += 1
        if i != N // i:
            dem += 1
print(dem)

import math

i = 0
n = 0
d = 0

n = int(input())
for i in range(1, int(math.sqrt(n)) + 1):
    if n % i == 0:
        if n // i == i:
            d += 1
        else:
            d += 2

print(d)
