Under the Hood · Live

6 Layers of retrieval. One enterprise-grade answer.

AskDSA retrieves across 10,000+ problems on 9 judges, fuses them through a 6-Layer RAG pipeline, routes to 25+ LLMs, then streams a full editorial - intuition, dry-run, code in Python / C++ / Java, pitfalls & edge cases. Watch it happen live.

Query Expansion + HyDE

2 GPT-5.2 calls → 4 semantic variants + a hypothetical solution doc.

Filter Detection

Platform + difficulty resolved into ChromaDB where-filters.

Multi-Vector Search

6 embeddings × 2 collections → up to 12 parallel ChromaDB queries.

RRF Merge + Boost

Reciprocal Rank Fusion (k=60) + keyword HybridScore reranking.

Problem–Solution Pairing

Problem + editorial chunks joined by problem_id into one context.

MMR Diversity Filter

Maximal Marginal Relevance returns exactly topK, no near-dupes.

Response Streaming

The routed LLM streams a full editorial back, token by token.

Core Capabilities

Not a chatbot. A DSA teaching engine.

Everything you need to actually understand a problem - the intuition, the trace, the code, and the pattern behind it.

Three teaching modes

Full-RAG DSA tutor, contest-tuned CP editorial, and sub-200ms fast lookup - the router picks per query.

Real-time streaming

SSE token streaming with a live cursor - watch the editorial form.

Code in 3 languages

Every solution in Python, C++ and Java - syntax highlighted, copy-ready.

def two_sum(nums, t):
  seen = {}
  for i, x in enumerate(nums):
    if t - x in seen:
      return [seen[t - x], i]
    seen[x] = i

Dry-run trace tables

The most important teaching tool - step-by-step traces, never skipped.

Why AskDSA?

A generic model guesses. A static editorial can't adapt. AskDSA retrieves the real problem and solution, then teaches you the intuition - grounded, not hallucinated.
