Problem: In this problem you will be given a range 'n', and you are supposed to find all composite numbers within that range. Make your program efficient as time limit of the program is set to 1 second. Choose an efficient algorithm to find all the composite numbers within the range 0 to n.

Input

n - a single positive Integer.

Output

Space separated composite-numbers within the range of 0 and n.

Constrains

1 ≤ n ≤ 10000

SAMPLE INPUT
8

SAMPLE OUTPUT
4 6 8

Solution (in PYTHON):

Solution:
def primes1(n):
    """ Returns  a list of primes < n """
    sieve = [True] * (n/2)
    for i in xrange(3,int(n**0.5)+1,2):
        if sieve[i/2]:
            sieve[i*i/2::i] = [False] * ((n-i*i-1)/(2*i)+1)
    return [2] + [2*i+1 for i in xrange(1,n/2) if sieve[i]]

allPrimes = primes1(10000)
ins = input()
for x in range(2, ins+1):
    if x in allPrimes:
        continue
    print x,
