  • Converting Messy Documents to Markdown in Enterprise RAGJun 23, 2026. If you have built an enterprise Retrieval-Augmented Generation (RAG) system, you already know the dirty secret of the industry: The LLM is rarely the bottleneck; the data ingestion pipeline is. Enterprises do not store their knowledge in neat, pre-formatted JSON files. Knowledge is trapped in 50-page PDFs with complex tables, nested DOCX onboarding guides, and legacy TXT configuration logs. If you naively extract text from these files and chunk them using a simple character-count splitter, your RAG system will suffer from "context fragmentation."

  • Count Elements in a Given Range Using Sorting and Binary SearchJun 06, 2026. This problem involves finding the number of elements in an unsorted array that lie within a given range [a, b] for multiple queries. A naive approach would check each element for every query, resulting in high time complexity. A more efficient solution uses sorting and binary search: Sort the array to enable fast searching. For each query [a, b]: Use a lower bound search to find the first element = a. Use an upper bound search to find the first element > b. The difference between these indices gives the count of elements in the range. This approach significantly reduces time complexity to O(n log n + q log n) while keeping space usage minimal. It’s a classic example of combining sorting with binary search to handle range-based queries efficiently.
