contiguous storage, binary trees, binary tree traversal, searching insertion and deletion in
binary trees, heap tree and heap sort algorithm, AVL trees.
Section C
Graphs and their application, sequential and linked representation of graph – adjacency
matrix, operations on graph, traversing a graph, Dijkstra’s algorithm for shortest distance,
DFS and BFS, Hashing.
