Data Structures & Algorithms

A book-shaped table of contents for MAANG-interview DSA prep: Python language foundations, mathematical and algorithmic foundations, arrays/strings, linked structures, stacks/queues, trees, graphs, sorting/searching, dynamic programming, greedy algorithms, backtracking, bit manipulation, advanced data structures, advanced algorithms, interview problem patterns, and MAANG interview mastery — a book-length progression from fundamentals to Google/Meta/Amazon/Apple/Netflix/Microsoft (L4–L6) interview readiness.

1 — Complexity Analysis in Interviews

Stating brute-force and optimized complexity out loud, in the form interviewers actually expect to hear it.

10 — Revision Strategy & Cheat Sheets

Spaced-repetition strategy and one-page cheat sheets for keeping all 130 chapters' patterns fresh in the weeks before an interview.

2 — Choosing the Right Data Structure

A decision framework for picking the right structure from constraints alone — before writing a line of code.

4 — Problem-Solving Framework

Clarify constraints, brute force first, identify the pattern, optimize, code, test edge cases — the repeatable loop for an unseen prompt.
