DIV - Divisors

Let N be a positive integer. In theory it is easy to decide if d(N) (the number of positive divisors of N including 1 and N) is prime or not. Your task is just a little bit harder: compute all N in [1,10^6] for which d(N)=p*q where p and q distinct primes.

Input

There is no input for this problem.

Output

To make the problem less io related write out only every 9-th of them, one per line.

Output:
50
99
162
...
999524
999728
999927

Note for archive : this problem was on Pyramid before this day, now on cube. EB don't have hands on those changes.

nyc question...A/C in one go...

Requires no specific algorithm or high class number theory only about optimizing the time and a perfect implementation.

@Aditya Kumar Akash 32 should alse be there in the output, then the 9th number will be 50.

Interesting. Up to 3rd number my algorithm works fine, but the final 3 I'm getting
999664
999825
999988

Can anyone please explain the output ? How 50 comes first -- getting 12, 18, 20, 28, 44, 45, 48 ,50 ,52 as first 9 elements of entire sequence -- so first in output should be 52.

The largest part of the execution time is "factorsieve",so just adjust algorithm
of this part.

Nice problem...:)

In order to pass the time limit, you don't need to know any special number theory.
Good implementation is enough

@Govardhan Reddy M : the no. u missed was 30.. better luck.. :P
