Q1 a) Define data structure and categorize them into various types based on their organization and representation, with suitable examples.
b) Define an algorithm with suitable examples. What are the various attributes of an algorithm explain? (4+3)
Q2. a) What are the merits and demerits of a linear queue over circular queue? Explain an Application of circular queue data structure.
b) Explain the relative merits and demerits of linked data structures over sequential data structures with suitable example. (4+3)
Q3.Write a function search(p, x) that accepts a pointer p to a, singly linked, list of integers and an integer x and returns a pointer to node containing x, if it exists and NULL otherwise. Write a function searchjnsert (p, x), that adds x to list(pointcd lo by p) if it is not found and returns a pointer to node containing x. (7)
Q4 a) Draw the binary expression tree for the expression given below and write the prefix and postfix form of the expression.
