Data Structures and Algorithms

Weeks 1-2: Data Structures & Algorithms fundamentals. Solve 5-10 problems per topic.

Weeks 1-2: Focus on core data structures and algorithms. Cover arrays, linked lists, stacks, queues, trees (binary trees, BSTs, AVL trees), heaps, hash tables, and graphs. Practice algorithms like sorting (quicksort, mergesort), searching (binary search), recursion, dynamic programming, and graph traversal (BFS, DFS). Aim to solve at least 5-10 problems per data structure/algorithm type.
