CSP-S 2022 Solutions
The problems in this set require careful handling of edge cases and efficient algorithms. Below are the solutions for all four tasks.
T1: Holiday Plan
Given constraints n ≤ 2.5 × 103, an O(n2) approach is feasible.
We enumerate the middle two vertices B and C. For a valid pair (B, C), we pre‑compute the set of possible A (from B) and possible D ...
