The link isn't working.

Still, you don't need to feel that bad about the 600 problem — the systemtest for it was dyed in bloody red.

Like I ranted before: TC should have pretests, it's too random this way. I was successfully challenged on both problems I thought I'd managed to solve successfully in the last round I competed in; this time, I got 19. place. Random stuff.

    I have uploaded the picture in another "free uploading" server. Does it works now?

    Yes, you are right, the 600p was tricky. But the fact is that I failed only by mistyping a variable name.

    I agree that stronger pretests would make it better, but there is always a way to fail system test that pretest can't save you.

Just curious about the random function, suppose we don't use some seeds (like srand() in C++) then is it true that the function will always return the same number for the same arguments?

    Java's Math.random() is making a new instance of Random class when first called and then uses this instance to make random doubles. To use custom seeds, you should use Random class directly.

Don't worry bro, sometimes even my submissions fail (nod).
