Definition (from Wikipedia):

A natural number is called a prime number (or a prime) if it is bigger than one and has no divisors other than 1 and itself. For example, 5 is prime, since no number except 1 and 5 divides it. On the other hand, 6 is not a prime (it is composite), since 6 = 2 × 3.

The input file **DATA2.txt** will contain 5 lines, with each line having an integer `N` where 5 ≤ `N` ≤ 10000.

The output file **OUT2.txt** will contain 5 lines. Each line contains the sum of all the primes less than the corresponding input `N`.
