Data Structures and Algorithms

Weeks 1-2: Data Structures & Algorithms fundamentals. Practice coding problems daily.

Weeks 1-2: Focus on core data structures (arrays, linked lists, trees, graphs, hash maps) and algorithms (sorting, searching, dynamic programming, graph traversal). Practice implementing these from scratch and analyze their time and space complexity. Aim for at least 2-3 coding problems per day.
