This module introduces graph and tree data structures, exploring their properties and traversal methods. Students will learn about heaps and heap sort, priority queues, binary trees, n-ary trees, binary search trees, and trie trees. The module also covers advanced topics such as Kruskal’s Minimum Spanning Tree algorithm, Dijkstra's shortest path algorithm, disjoint sets, Floyd-Warshall's algorithm, breadth-first search (BFS), depth-first search (DFS), AVL trees, B-trees, and threaded trees.
