It is supposed to be that way.Still, there is no update in the standings yet for the one who has attempted a hack.I think the score for the hacking attempts will be rejudged during final system tests.

right

You may want to use CF predictor extension in Google Chrome.It shows you an assumption of what your ratings increase or decrease will be.It has always given me perfect rating change.

If your solution is hacked,you will be able to see it in your submissions.It is informed on the moment whenever your code goes hacked.

The ratings update takes some time..But it is quite sure to be updated within an hour or two.

Thank you very much.I noticed that now.I thought any permutation is acceptable.But problem statement says 1 to n inclusive indeed. :(

In test case 6 of problem B:
10

1 2 3 4 5 6 7 8 4 10

1 2 3 4 5 6 7 6 9 10

my output is :

1 2 3 4 5 6 7 6 4 10

Jury's answer was :

1 2 3 4 5 6 7 8 9 10

But the problem says,it satisfies any permutations maintaing (n-1) matches..I can't find any errors with my output.It would be very helpful if someone helps me with my confusion.Thanks in advance.
