Ohh damn, that explains why 2-3 very not really high rated folks solved D.

Don't know if other problems had the similarity. But for problem C, this isn't a fair criticism.

Because for this problem C, figuring out we need to find the maximum XOR subarray is the main part. After that, One doesn't need to use any Trie or anything. Constraints on values are so small, one can check for each position for all possible previous prefix sums till now.

What's the idea for the solution to Problem F? I have gotten a bunch of insights but haven't been able to formulate the complete solution.

Is anyone left for taking part in the contest?

Did you practice specifically for solving the problems <= 2300 faster? \

Like only practicing loads of those outside the contest or something else?
