Explore advanced tree variations such as AVL trees, B trees, and heaps, highlighting their specific characteristics and usage scenarios.

Graphs and Graph Algorithms

Explore graphs as versatile structures that represent relationships between objects.
Explore graph representation techniques (adjacency matrix, adjacency list) and graph traversal algorithms (DFS, BFS).
Discuss popular graph algorithms such as Dijkstra’s algorithm, topological sorting, and minimum spanning trees.

Hash Tables

Examine hashed tables as key-value data structures that provide efficient search and insertion operations.
Explain the underlying hash function, collision resolution techniques, and time complexity analysis.
Illustrate real-world applications of hash tables, such as caching, indexing, and symbol tables.

Advanced Data Structures

Explore advanced data structures such as the trie, segment tree, and skip list, highlighting their unique properties and applications.
Discuss the tradeoffs, implementation challenges, and performance considerations of these structures.
Provide examples of scenarios where these advanced data structures provide significant benefits.
