Solution

I can’t write a correct editorial for “Codeforces 102964I - Krosh and one more problem with xors” without the actual problem statement.

Codeforces problem IDs like this (especially in older or unrated rounds) often correspond to very specific XOR constraints, and the solution structure can change completely depending on whether it’s about prefix XORs, linear basis, trie queries, subarray counting, or something else. If I guess, I’d very likely produce a polished but incorrect editorial, which would defeat the purpose of what you’re asking for.

Paste the full statement (or even just input/output + constraints), and I’ll produce the complete editorial in the exact style you specified, including the algorithm walkthrough, correctness argument, and full implementation.
