### 11825 - Hackers' Crackdown

Hi all, I'm trying to solve the problem [1] through backtracking, but it is timing out. Does anyone have ideas for solving it? I couldn't devise a dynamic programming solution. Random thoughts: - A minimal cover S is a subset of vertices such that all other vertex not in S are adjacent to someone in...

I have this problem too, but I use Firefox and deleting cookies solves the problem.
 sorry, it seems to be working already.

### I'm confused when we have a sequence of length 1.

When n = 1 and any m, shouldn't we print :

Code: Select all

``1``
This sequence does not violate any rule, because k = 1:
1) a[1] = 1 and 1 < i <= 1. since there's no such i, that's ok.
2) 1 <= i < 1 the same as above.
3) a[1], also ok.

But I was getting wa when assuming this...
Could someone explain me?

Yeah, I think

Code: Select all

``2222``
should output

Code: Select all

``222``
Rule 3 says you have to do Y2Y, and Y is a product from a number X. So the recursion is necessary.

If rule 2 required recursion, I think it should state something like this:
2X produces Y where X produces Y.
