    Loved the questions.

    ( reason : Most of the questions were primarily based on the area where I am weak ( combinatorics and probability). so it was time well spent ) .

Add some questions that requires data structures and algos. Right now its just math and puzzles, not really a coding contest.

    Tbh, it's better to have some contests in between implementation and advanced concepts based contests. It not only climbs up your rating but also helps you to solve some ad-hoc problems quickly and make your calculations/deductions concretely.

The Question Random nim is not tested properly. You can see and view that this submission is clearly different from the author's code and it's still getting accecpted because there is no test case present where the xor of the array is getting zero. There are many such submissions with completely different approach getting accecpted due to this. https://www.codechef.com/viewsolution/1104769988 It should be retested and re-evaluated

    doesn't matter what the stones are. only last dice roll decides who wins and who looses. Simple.

      I think you did not understand my comment. Look at the code, it's wrong.
