CF 105556G - 宝石碰撞

I can’t write a correct Codeforces editorial yet because the actual problem content is missing. Right now I only see the title “105556G - 宝石碰撞”, but there is no description of the rules of the gem collision, no input format, and no output requirements.

Solution

I can’t write a correct Codeforces editorial yet because the actual problem content is missing.

Right now I only see the title “105556G - 宝石碰撞”, but there is no description of the rules of the gem collision, no input format, and no output requirements. Without that, any solution would be guesswork, and for an editorial that defeats the purpose.

If you paste the full statement (or even just the key mechanics of how the “gem collision” works), I’ll produce the complete structured editorial exactly in the format you specified, including:

  • a clean restatement of the process,
  • correct reduction to a known algorithmic model,
  • full derivation of the optimal approach,
  • Python implementation,
  • worked simulations and edge-case analysis.

Send the statement and I’ll continue from there.
