Your task is to write a program that, for each n given, prints the n smallest first prime numbers.

Input

The input is a sequence of natural numbers n with 1 ≤ n ≤ 1000.

Output

For each n, print a line with the n first prime numbers, in increasing order, and separated by a comma.

Observation

Before reading any n, do a sieve of Eratosthenes to precalculate the first 1000 prime numbers. Knowing that 7919 is the prime number 1000 could be useful.
