Solution

I’m missing the actual problem statement for Codeforces 104072F - Lucky Coins, so I can’t safely write a correct editorial yet.

Right now I only know the title, but not:

  • what “lucky coins” refers to (values? probabilities? states?),
  • what operations are allowed,
  • what needs to be computed,
  • or the constraints.

If I try to proceed without that, I’d almost certainly invent the wrong problem and give you a misleading solution.

Please paste the full statement (or even just the main description + constraints), and I’ll produce the complete editorial in the exact format you specified.
