Here is a concise roadmap for learning Data Structures and Algorithms:

  1. Basic data structures: Arrays, Linked Lists, Stacks, Queues, Trees, Graphs
  2. Sorting algorithms: Bubble sort, Insertion sort, Selection sort, Quick sort, Merge sort, Heap sort
  3. Search algorithms: Linear search, Binary search
  4. Advanced data structures: Heaps, Tries, Hash tables, Bloom filters
  5. Algorithm design techniques: Greedy algorithms, Dynamic programming, Divide and conquer, Backtracking
  6. Graph algorithms: Breadth-first search, Depth-first search, Shortest path algorithms (Dijkstra, Bellman-Ford), Minimum Spanning Tree (Kruskal, Prim)
  7. Complexity analysis: Time and space complexity, Asymptotic notation (Big O notation)
