| Data Structure / Algorithm | Time (Avg) | Time (Worst) | Space Complexity | Best Use Case |
|---|---|---|---|---|
| Array / Dynamic Vector | O(1) Access | O(N) Search | O(N) | Direct indexing, contiguous memory cache locality |
| Hash Table / Hash Map | O(1) Lookup | O(N) Collision | O(N) | Fast key-value pair lookups and frequency counting |
| Balanced BST (AVL / Red-Black) | O(log N) | O(log N) | O(N) | Ordered data, range queries, C++ std::map |
| Min / Max Binary Heap (Priority Queue) | O(1) Peek Min | O(log N) Insert/Del | O(N) | Dijkstra algorithm, Top-K elements, Huffman Coding |
| Merge Sort | O(N log N) | O(N log N) | O(N) Aux Space | Stable sorting, linked list sorting, external sort |
| Quick Sort | O(N log N) | O(N²) Worst Pivot | O(log N) In-Place | Fastest in-memory sort with random pivot |
| Graph BFS / DFS | O(V + E) | O(V + E) | O(V) | Shortest path in unweighted graph (BFS), cycle check (DFS) |
