Solution

I’d like to write the full editorial, but I can’t reliably identify which problem “Codeforces 106122G - The Missing Bone” is from.

The available sources do not contain the statement for that problem, and “The Missing Bone” matches multiple unrelated problems and documents. I don't have the actual input/output specification needed to derive a correct solution.

Please paste one of the following:

  1. The complete problem statement, or
  2. A screenshot of the statement, or
  3. The input/output format together with the sample tests.

Once you provide it, I can produce the full competitive-programming editorial in the exact structure you requested:

  • Problem Understanding
  • Approaches
  • Algorithm Walkthrough
  • Python Solution
  • Worked Examples
  • Complexity Analysis
  • Test Cases
  • Edge Cases

with a complete proof of correctness and accepted Python implementation.
