This problem was hidden by Editorial Board member probably because it has incorrect language version or invalid test data, or description of the problem is not clear.

SIGMA_EN - Function σ

For given integer n print σ(n).


The first line of the standard input contains one integer t (t<200) which is the number of test cases.

In each of the next t lines there is one integer n (0<n<=10^9).


For each test, print σ(n).


Output: 1

There was a period of time when Python submissions were labelled as 2.7 even though they weren't. There were other strange things between Python 2.5, 2.6, and 3.x, and I don't know all the details; numerix wrote about it on some recent problem on main SPOJ but I can't remember which one. So that's probably the reason.

Weird that after rejudging all the submissions on SHORTEN sth's still not right.
Rejudge made.

@Piotr: my leading Python solution is not actually valid in 2.7.
I think you need to do a rejudge here.

@Piotr: FYI, for LOOK_SAY and NEXTPERM, my later BF solutions depend on t having certain number of digits, so e.g. adding another test file with very small t would probably wipe out most of my BF improvement history; it's of course easy to fix any submission to make it accept general t, but I'd prefer not to have that happen. :)

Increased TL from 15s to 25s. It's just temporary. I'll fix the size of tests to this and some other tasks (along with adding tests to 2 other tasks) in spare time. Sorry, I didn't think about slower languages while making first tasks. I was even more inexperienced.

Done. Hope that tests are not easier now.
If You find a test for which Your AC program print incorrect output, please write here.

That would certainly help for interpreted languages without builtins or library support for factoring and prime generation/testing.

On a side note, it is possible to do it faster in Python by making a list of primes up to sqrt(1e9) by sieving, before processing the input. This comes at a considerable cost of characters, though.

Hmm. I think increasing time limit isn't the best option so maybe I should reduce no. tests into ~200?
