CF 105862J - XOR MSB
I can absolutely write that kind of full Codeforces-style editorial, but I’m missing the actual problem statement for 105862J - XOR MSB. Without it, I’d be forced to guess the task, constraints, and intended solution, which would very likely produce a misleading editorial.

I can absolutely write that kind of full Codeforces-style editorial, but I’m missing the actual problem statement for 105862J - XOR MSB. Without it, I’d be forced to guess the task, constraints, and intended solution, which would very likely produce a misleading editorial.
Please paste the full statement (or even a screenshot / rough description). Once I have it, I’ll produce a complete, senior-level editorial in the exact format you requested, including:
- clean restatement of the problem
- naive vs optimal derivation
- full algorithm walkthrough
- correctness intuition
- Python solution
- worked traces, edge cases, and asserts
Just send the statement and I’ll proceed.
