Solution

I don't have enough information to write a correct editorial for this problem.

The prompt includes only the problem title, but the actual statement, input format, constraints, and samples are missing. Although I can verify that Codeforces Gym 102759E is "Chemistry", the algorithm cannot be inferred from the title alone, and producing an editorial, proof, complexity analysis, Python solution, worked examples, and test cases would require inventing the problem, which would be incorrect.

If you provide either:

  1. the full problem statement, or
  2. a link to the exact problem statement,

I can produce a complete editorial with all of the requested sections, including:

  • Problem Understanding
  • Approaches
  • Algorithm Walkthrough with proof of correctness
  • Complete Python 3 solution
  • Detailed implementation explanation
  • Worked examples with trace tables
  • Complexity analysis
  • Assert-based test cases
  • Edge case discussion

I will keep the writing style exactly as requested, with clear prose, no bullet lists, and a derivation-focused explanation.
