Problem 207. hackathon impossible

Created by Alfonso Nieto-Castanon

Solve Later

You might have found a solution to our previous hackathon entry, or its sequel but do you think you can do that (yet) again?

As before, I am thinking of a number between 1 and 10000... can you guess what this number is?

Description

The test suite has random entries. Your job is to find a hack and have your function return the correct answer.

notes

Neither the @bmtran's evalin trick nor a lookup table nor the solution to our previous hackathon entries would work here...

There is something very strange about the contest system RandStream... it keeps reverting to a 'legacy' mode randomly. I submitted the same solution several times in a row and kept getting an error since the legacy mode has the State in a cell format. Finally I lucked out and got it to default back to the standard format.

I observed the same effect, it is rather interesting, my guess was that other people submissions including rand('state',...) commands might be producing this (I imagine we should be sharing a matlab session for this to happen, the context might be running on some sort of distributed environment, I am not sure about the details...)
