Data Structures & Algorithms Fundamentals
Weeks 1-2: Data Structures & Algorithms (Arrays, Lists, Trees, Graphs, HashMaps, Sorting, Searching, DP). 2-3 medium LeetCode problems/day.
Weeks 1-2: Focus on core data structures and algorithms. Master arrays, linked lists, stacks, queues, trees (binary trees, BSTs, heaps), graphs, and hash tables. Practice common algorithms like sorting (quicksort, mergesort), searching (binary search), graph traversals (BFS, DFS), and dynamic programming. Aim for 2-3 medium LeetCode problems per day.
