        Hidden test cases are added everyday. If your code passes hidden test cases your score will remain same else it will decrease day by day. Wait until contest ends, your score will decrease if it fails on new hidden test cases.

          Tomorrow my code was showing Preliminary passed and today its showing Accepted, so it means system testing has accepted my solution. Otherwise it should still show preliminary

            Well it does show Accepted but it still does run on additional cases after every day.
            I had a solution which failed on 2 consecutive days when I fixed it after the 1st fail and got full points for that day.

              If your solution fails and you resubmit then again your code is tested on those hidden cases next day. But if you don't resubmit then it will not be checked again and again every day

        The above screenshot shows that your submission for the problem is graded on all cases including hidden and you have got 20 scores. If the solution is not graded on hidden cases then "Preliminary" will be written alongside the score.

          Yes, you are right.My submissions has been checked for all hidden cases. The problem is that One of my wrong submission is Accepted. It prints "No" for the testcase I mentioned above while the correct answer is "yes". This test case should be included and all submissions should be rechecked

I was trying to submit two minutes before the contest but the editor was refreshing ad refreshing displaying the old version of my code :( I tried with chrome and firefox. I think this issue affected my score because my last code was correct but I couldn't submit it.

Why would you add so many weak tests for the problem DAG queries? The problem loses its purpose if you allow O(n+m) solutions per query to get more than 60 points. For example, this code: https://www.hackerrank.com/rest/contests/w25/challenges/dag-queries/hackers/akshayv3/download_solution

Yes, you are right.My submissions has been checked for all hidden cases. The problem is that One of my wrong submission is Accepted. It prints "No" for the testcase I mentioned above while the correct answer is "yes". This test case should be included and all submissions should be rechecked. Have a look at dubai tour package, singapore packages, mauritius package,thailand tour packages, malaysia tour package, hongkong packages,srilanka tour package, turkey tour packages, Europe tour packages from India and Bali Honeymoon Tours, South Africa Safari Tour Package, Holy Land Tour, Maldives Tour Package, USA Package which are the best.

Hey, I am not ready to face this challenge. Because, it will be very tough to find right answer for your question. Moreover, I don't have enough knowledge in programming. Please, Can you provide simple challenging question for me?
