CS3301 - Data Structures Important Topics (Unit-wise)

Data structures are essential for writing efficient programs and solving problems in a systematic way. A strong understanding of linked lists, stacks, trees, graphs, and hashing helps students improve algorithm design, reduce time complexity, and perform better in university exams.

Unit I - Linked Lists and Polynomial ADT

This unit introduces linear data structures and their practical use in memory-efficient programming. Focus on pointer-based implementation, node creation, and common linked list operations.

  • Singly linked list
  • Doubly linked list
  • Circularly linked list
  • Polynomial ADT

Unit II - Stack and Queue ADT

This unit covers stack and queue-based problem solving, which is widely used in recursion, expression evaluation, and scheduling algorithms. Learn the operations, conditions, and standard applications carefully.

  • Applications of stack
  • Stack ADT
  • Deque
  • Circular queue

Unit III - Trees and Heaps

This unit explains hierarchical data representation and priority-based processing. Practice tree operations and understand how heaps support efficient selection and arrangement of data.

  • Tree traversal
  • Binary search tree
  • Binary heap
  • AVL tree

Unit IV - Graphs and Advanced Trees

This unit focuses on graph traversal and advanced tree structures used in indexing, routing, and shortest path problems. Understand algorithm logic and compare different graph techniques clearly.

  • B-tree and B+ tree
  • BFS and DFS
  • Dijkstra's algorithm
  • Prim's algorithm and Kruskal's algorithm
  • Euler circuit

Unit V - Searching, Sorting and Hashing

This unit is important for algorithm analysis and fast data retrieval. Revise searching, sorting, and hashing carefully because these topics often appear in both theory and problem-solving questions.

  • Binary search
  • Insertion sort, selection sort, and merge sort
  • Closed hashing with open addressing
  • Extendible hashing

Exam Preparation Tips: Revise each unit with diagrams, algorithm steps, and dry-run examples. Practice linked list, tree, and sorting programs regularly, and compare time complexity, space complexity, and use cases before the exam.
