This page may have been moved, renamed, or deleted. ## Suggested Pages You may be looking for one of the following: - [17.5 B-Tree Performance](https://cs61b-2.gitbook.io/cs61b-textbook/17.-b-trees/17.5-b-tree-performance.md) - [27.4 Real World Examples](https://cs61b-2.gitbook.io/cs61b-textbook/27.-software-engineering-i/27.4-real-world-examples.md) - [25.2 Prim's Algorithm](https://cs61b-2.gitbook.io/cs61b-textbook/25.-minimum-spanning-trees/25.2-prims-algorithm.md) - [18.2 Creating LLRB Trees](https://cs61b-2.gitbook.io/cs61b-textbook/18.-red-black-trees/18.2-creating-llrb-trees.md) - [27.3 Strategic vs Tactical Programming](https://cs61b-2.gitbook.io/cs61b-textbook/27.-software-engineering-i/27.3-strategic-vs-tactical-programming.md) ## How to find the correct page If the exact page cannot be found, you can still retrieve the information using the documentation query interface. ### Option 1 — Ask a question (recommended) Perform an HTTP GET request on the documentation index with the `ask` parameter: ``` GET https://cs61b-2.gitbook.io/cs61b-textbook/17.-b-trees/17.5-b-tree-performance.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. ### Option 2 — Browse the documentation index Full index: https://cs61b-2.gitbook.io/cs61b-textbook/sitemap.md Use this to discover valid page paths or navigate the documentation structure. ### Option 3 — Retrieve the full documentation corpus Full export: https://cs61b-2.gitbook.io/cs61b-textbook/llms-full.txt Use this to access all content at once and perform your own parsing or retrieval. It will be more expensive. ## Tips for requesting documentation Prefer `.md` URLs for structured content, append `.md` to URLs (e.g., `/cs61b-textbook/17.-b-trees/17.5-b-tree-performance.md`). You may also use `Accept: text/markdown` header for content negotiation.
