Data Structures & Algorithms

Pattern-first DSA preparation for FAANG interviews. Each topic — Heaps, Intervals, and more to come — is a chapter containing a theory primer plus pattern groups, with dual-language solutions and edge-case checklists for every problem.

WHAT YOU’LL LEARN

What you’ll learn

  1. Recognise the underlying pattern in any DSA interview question before reaching for code.
  2. Build a library of reusable templates — interval sweeps, heap top-K, two-pointer scans — that compose across problems.
  3. Reason about time and space trade-offs out loud the way interviewers expect.
  4. Walk through forty FAANG-grade problems across Heaps (16) and Intervals (22), each with Python and TypeScript solutions.
