I can do this, but the problem statement in your message is corrupted and incomplete. Several critical pieces are missing or malformed: - The first line says The first line contains one integer t, but the sample input does not contain t.

Solution

I can do this, but the problem statement in your message is corrupted and incomplete.

Several critical pieces are missing or malformed:

  • The first line says The first line contains one integer t, but the sample input does not contain t.
  • The sample input itself starts with
4 5
1 2 3
1 3 4
2 3 2
3 4 1
2 4 1
2 2
1 10 1
20 30 2
1 10 1
20 30 3

which looks like a single test case, not four test cases.

  • The sample output section is empty and replaced by page headers:
Page 10 of 14
Inter University Programming Contest - MU CSE Fest 2025
  • The upper bound for M is corrupted:
1 ≤ M ≤ N (N2−1)

so the intended density of the graph is unclear.

Before writing a complete editorial with proof, code, worked examples, edge cases, and test cases, I need the original statement or at least a clean PDF screenshot of Problem F, because otherwise I would have to guess the exact input format and expected behavior.

Please paste the original statement or upload the PDF page containing Problem F, and I can then produce the full editorial in the format you requested.
