Foundational Concepts
Weeks 1-2: Data Structures & Algorithms (Easy/Medium).
Weeks 1-2: Focus on core data structures (arrays, linked lists, trees, graphs, hash tables) and algorithms (sorting, searching, dynamic programming, graph traversal). Practice implementing these from scratch and analyze their time and space complexity. Solve LeetCode problems tagged 'Easy' and 'Medium'.
