Data Structures & Algorithms

Weeks 1-2: Data Structures & Algorithms (LeetCode Medium)

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 in your preferred language and analyze their time and space complexity. Aim for 2-3 LeetCode medium problems per day.
