    sorry bro, but I didn't got you. Can you explain more, or refer to some link where I can study about this rule violation thing.

    UPD: thanks, I got rid of at least runtime error.

    UPD-2:Finally, got AC. And, thanks a lot bro, you guys are awesome. There was no way I could have figured reason by myself. This community is awesome!

      A comparison function should return true if the first argument is less than (i.e. is ordered before) the second in the strict ordering relation, and false otherwise.
