Can you replace a problem in GameTheory category. It is worth replacing with same category and same difficulty, TBH :slight_smile:

It’s simple…first take rows of even sizes, each player will get half… Then take all rows of odd sizes and sort them according to the middle element and alternate sum by one turn including middle element and next turn excluding it

The problem statement never said that chef/Ramsay can’t jump to a different row in order to maximize their amount.

He can take from any non-empty pile. So it’s implied that he can jump maybe

So suppose a line is:
1 99 2 3 4 …
So chef should be smart enough to go out of his way and pick 1 so that in next turn he is able to pick a huge number.

I don’t have the whole input now, I’ll post it as soon as I get home

Thank you for reporting this issue. But you had no business making such a post about a problem from an ongoing contest. If you have an issue, comment it or send us an email. But posting it publicly without even waiting for a response from us is unacceptable. And neither is it acceptable for you to accuse someone of copying without any evidence. Two same/similar problems do not mean copied problems, particularly for problems which are as natural as this.

All that said, we are very sorry for not having caught this before the contest. We hope to get the replacement problem ready soon.

Both player would first tackle the odd rows

Imagine these 3 rows

9
8
3 3

Chef would first pick 9 and ramsay would pick 8 and the chef 3 and ramsay 3
