Solution

I don't have enough information to write a correct editorial for this problem because the statement is incomplete in your prompt, and the key part of the problem, the effort formula, is embedded as an image that is not available as text. The Codeforces page also exposes it only as an image, so I cannot recover the mathematical definition from the page.

Without that formula, I cannot correctly derive:

  • the algorithm,
  • the proof of correctness,
  • the implementation,
  • the worked examples, or
  • the test cases.

For example, the samples are consistent with several different effort definitions except for one hidden detail contained in the missing image.

If you paste the missing formula (or the full problem statement), I'll produce the complete editorial in exactly the format you requested, including:

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

with a full proof, implementation, traces, and explanations.
