Welcome to the A Dev Writes DSA series. This collection is designed to take you from the basics to advanced algorithmic problem solving.
We’ve organized the course into modules. Each module starts with the fundamental theory behind the data structure, followed by a curated list of practice problems found in technical interviews.
1. Array
Arrays are the building blocks of data structures. Learn memory layout, access patterns, and in-place algorithms.
2. Strings
Understand immutability, the string pool, and efficient string manipulation techniques.
3. Linked List
Master pointer manipulation with Singly, Doubly, and Circular Linked Lists.
👉 Start Module 3: Linked Lists
4. Trees
Explore hierarchical structures including Binary Trees, BSTs, and traversals (BFS/DFS).
5. Graphs
Dive into network modeling with standard traversals, shortest path, and topological sort.
