Data Structures & Algorithms

Weeks 1-2: Data Structures & Algorithms (Core)

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