CF 106513B - Support Beam

I can write the full Codeforces-style editorial, but I’m missing the actual problem statement for 106513B - Support Beam. Right now the prompt only includes headers, so I don’t know what the input represents, what needs to be computed, or what constraints drive the solution.

Solution

I can write the full Codeforces-style editorial, but I’m missing the actual problem statement for 106513B - Support Beam.

Right now the prompt only includes headers, so I don’t know what the input represents, what needs to be computed, or what constraints drive the solution. If I tried to proceed anyway, I’d be forced to guess the task, which would produce a misleading editorial.

Paste the statement (or even a screenshot / rough paraphrase), and I’ll turn it into a complete, senior-level walkthrough with solution, proof idea, code, and edge-case analysis in the format you specified.
