CF 102791A - Christmas Ornaments

I don't have the actual problem statement for Codeforces 102791A "Christmas Ornaments". The prompt you provided has empty sections for the statement, input, and output, so I don't know what the task is asking or what algorithm is required.

Solution

I don't have the actual problem statement for Codeforces 102791A "Christmas Ornaments". The prompt you provided has empty sections for the statement, input, and output, so I don't know what the task is asking or what algorithm is required.

Without the problem statement, I can't correctly produce:

  • a solution editorial,
  • the algorithm,
  • a proof of correctness,
  • the Python implementation,
  • worked examples,
  • complexity analysis, or
  • test cases.

Please provide one of the following:

  1. The full problem statement (preferred).
  2. A link to the problem.
  3. A screenshot of the statement.

Once I have the actual problem, I'll write the complete editorial in the exact structure and style you requested, including all required sections, a correct Python solution, worked examples, edge-case analysis, and assert-based tests.
