Data Structures Notes PDF — 9-Page Exam Revision Guide with Python Code

Revise a full semester of Data Structures in one sitting.

Most notes are either too thin to be useful or 200 pages you'll never finish. This is the middle ground: 9 pages that cover everything your syllabus asks for, written to be read the week before your exam.

What's inside

• 11 chapters — Big-O, Arrays, Linked Lists, Stacks, Queues, Trees & BST, Heaps, Hashing, Graphs, Searching & Sorting
• 9 Python examples that actually run — copy them, run them, and the expected output is written beside each line
• Complexity tables for every structure and all six major sorting algorithms, including stability
• Exam tips on the formulas and comparisons that come up repeatedly in question papers
• A "which structure when?" table — the question interviewers and viva examiners love
• A one-page complexity cheat sheet for the night before your exam
• 8-question self-test to check whether it actually stuck

Who it's for
CSE, IT and BCA students in semesters 2–4, anyone preparing for placement aptitude and technical rounds, and self-taught developers who skipped the theory.

Format: PDF, 9 pages, A4. Reads well on phone, laptop and print.
