Below is a complete, self-contained DSA course note set with every code example in both C++ and Python, organized by modules. All code is tested, concise, and production-ready for interviews (LeetCode-style).

Here is a curated, leveled problem list for MODULE 1: ARRAYS & STRINGS Designed for progressive learning → Beginner → Intermediate → Advanced Includes LeetCode (LC), GeeksforGeeks (GFG), Codeforces (CF), and InterviewBit (IB) links.

Below is a complete, structured note set for the Data Structures and Algorithms (DSA) syllabus typically covered in undergraduate CS programs (e.g., GATE, university exams, interviews). The notes are divided into modules with key concepts, formulas, time/space complexities, code snippets (C++/Python), and practice tips.
