CF 105733D - Xử lí đồ thị

I can absolutely write that editorial, but I don't have the actual problem statement for Codeforces 105733D. The prompt you provided has empty sections for "Problem Statement", "Input", and "Output", so I don't know what the graph problem is asking.

Solution

I can absolutely write that editorial, but I don't have the actual problem statement for Codeforces 105733D. The prompt you provided has empty sections for "Problem Statement", "Input", and "Output", so I don't know what the graph problem is asking.

Without the statement, I cannot correctly derive:

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

Making these up would almost certainly produce an incorrect editorial.

Please provide one of the following:

  1. The full problem statement (preferred).
  2. The Codeforces link for 105733D.
  3. A screenshot or PDF of the problem.

Once I have the statement, I'll produce a complete editorial following all of your requested formatting and style requirements, including:

  • Problem Understanding
  • Approaches with brute force and optimal solution
  • Algorithm Walkthrough with proof sketch
  • Complete Python 3 solution using sys.stdin.readline
  • Detailed code explanation
  • Worked Examples with markdown tables
  • Complexity Analysis
  • Assert-based test cases
  • Edge Cases with concrete traces

I will also keep the writing style exactly as requested: clear senior-engineer prose, no bullet lists, no filler, no copied statement, and no em dashes.
