Data Structures and Algorithms

Weeks 1-2: Data Structures & Algorithms Fundamentals. Practice 2-3 LeetCode problems daily.

Weeks 1-2: Focus on core data structures (arrays, linked lists, stacks, queues, trees, graphs, hash tables) and their common algorithms (sorting, searching, graph traversal). Practice implementing these from scratch and analyze their time and space complexity. Aim for 2-3 LeetCode problems per day.
