Web search (Google, Duckduckgo, Stack Overflow) for questions related to your programming language and implementations of algorithms is allowed. However, you may not search for specific solutions to the problems featured.

You may use large language models (ChatGPT, Claude, Gemini, etc) to help discuss algorithms, approaches, and data structures, under these conditions:

• Give each problem an honest attempt with your team before consulting an LLM.
• You may not copy-paste the problem specification into the LLM input.
• You may not copy-paste ANY code from the LLM output.
