Course Objectives: This course is designed to:

  • Introduce the fundamental concept of data structures and abstract data types
  • Emphasize the importance of data structures in developing and implementing efficient algorithms
  • Describe how arrays, records, linked structures, stacks, queues, trees, and graphs are represented in memory and used by algorithms

Course Outcomes: After completing this course a student will be able to:

  • Summarize the properties, interfaces, and behaviors of basic abstract data types
  • Discuss the computational efficiency of the principal algorithms for sorting & searching
  • Use arrays, records, linked structures, stacks, queues, trees, and Graphs in writing programs
  • Demonstrate different methods for traversing trees


Data Structures – Definition, Classification of Data Structures, Operations on Data Structures, Abstract Data Type (ADT), Preliminaries of algorithms. Time and Space complexity. Searching – Linear search, Binary search, Fibonacci search. Sorting- Insertion sort, Selection sort, Exchange (Bubble sort, quick sort), distribution (radix sort), merging (Merge sort) algorithms.
