**Time:** **3 Hours ** ** Total Marks: 60**

**Note:**

**1.****Attempt any FIVE questions.****2.****Each question carries equal marks**

**Q 1** ** a. **Write an algorithm to transform an infix expression into a prefix expression. What is

** **the time complexity of the algorithm?

** b.** The order of nodes of a Binary Tree in Preorder and Inorder traversal are as follows:

**(a) **Insertion sort

**(b) **Application of Binary trees

Note: Above M.Sc Computer Science Sample Paper for 2nd year Data Structure and Algorithm has been prepared after reviewing few universities sample papers. We are not sure whether same or similar question papers pattern does your university has or not. We are just trying to help you by providing the possibilities. We always suggest you to go thoroughly with textbooks, teacher’s notes and the syllabus for better preparation of your coming examination.
