User: 

You are given access to make searches on the Internet. The format for making a search is:
1. After the user sends a message, you will decide whether to make a search. If you choose to make a search, you will output a single message, starting with the word <web_search>, followed by ONLY your web search query. After your search query, you must output the token </web_search> to denote the end of the search query. Keep your search query very concise.
2. The system will then append the web search results at the end of the user message, starting with the token <web_search_results>. Take note that the user CANNOT SEE the content after <web_search_results> - YOU should use these results appropriately to improve your response. Additionally, If the web search results are already present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should choose to search the web ONLY if ANY of the following circumstances are met:
1. User is asking about current events or something that requires real-time information (news, sports scores, 'latest' information, etc.)
2. User is asking about some term you are unfamiliar with (e.g. if it's a little-known term, if it's a person you don't know well, etc.)
3. User is asking about anything that involves numerical facts (e.g. distances between places, population count, sizes, date and time, etc.)
4. User explicitly asks you to search or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason. However, you must not refuse to search the web if the user asks you to do so.
If you are highly unsure about whether to make a search (e.g. if the user's query is vague or if you think you are unfamiliar with the query to a certain extent), you may directly ask the user for clarification.

When using web search results, you are encouraged to cite references where appropriate, using inline links in standard markdown format.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
Remember that you MUST NOT make up any false information.

User: What is pure functional programming
Assistant:  PurePure functional programming is a programming paradigm where computation is treated as the evaluation of mathematical functions without changing state or mutable data. In pure functional programming:

- Functions have no side effects, meaning they do not alter any state or data outside their scope.
- Given the same inputs, functions will always return the same outputs (referential transparency).
- There is an emphasis on immutability, so data cannot be modified once created.
- Control flow is often managed through recursion and higher-order functions rather than loops or conditional statements with side effects.

Examples of purely functional programming languages include Haskell and certain subsets of languages like Scala or F#. Pure functional programming promotes easier reasoning about code, better modularity, and concurrency without issues related to shared state. Would you like examples or more details on how it differs from other paradigms?
