Course Outcomes: The student will be able to :

Describe a computational solution to well-known problems like searching, sorting, etc.
Estimate the computational complexity of different algorithms.
Devise an algorithm using appropriate design strategies for problem-solving.

Question Paper Pattern:

The question paper will have ten questions.
Each full Question consisting of 20 marks
There will be 2 full questions (with a maximum of four sub-questions) from each module.
 • Each full question will have sub questions covering all the topics under a module.
The students will have to answer 5 full questions, selecting one full question from each module.
