📘 Data Structures Roadmap 🚀 Want to crack tech interviews? Focus on these must-know DSA concepts: 🔹 1. Arrays & Strings → Sliding window, two pointers, subarrays → Prefix sums, anagrams, longest substring 🔹 2. Linked Lists → Reverse, detect cycles, merge lists → Remove duplicates, palindrome check 🔹 3. Stacks & Queues → Valid parentheses, next greater element, monotonic stack → Implement stack with queue, circular queue 🔹 4. Trees & Binary Search Trees (BST) → Level order, DFS, lowest common ancestor → Validate BST, tree diameter, serialization 🔹 5. HashMaps & Sets → Frequency maps, anagrams, hashing tricks → Subarray sums, group anagrams 🔹 6. Recursion & Backtracking → Subsets, permutations, N-Queens → Word search, combinations, Sudoku 🔹 7. Dynamic Programming (DP) → 0/1 Knapsack, Longest Common Subsequence, Memoization → Fibonacci, house robber, edit distance 🔹 8. Graphs → BFS, DFS, Union-Find, Dijkstra's Algorithm → Topological sort, shortest path, cycle detection 🔹 9. Heaps & Priority Queues → Top K elements, heapify, median in stream → Merge K sorted lists, kth largest 🔹 10.
