Description: Create Anki flashcards for USACO Platinum competition prep, especially US Open Invitational 2026. Use when: generating USACO study cards, creating platinum algorithm cards, reviewing competitive programming topics (segment trees, DP, graph algorithms, network flow, strings), making cards from past USACO problems or USACO Guide material. Cards cover theory (derivations, complexity proofs, invariants) and implementation (C++ code patterns with syntax highlighting). Output is a tab-separated .txt block ready to import into Anki.
