Computer Science Engg. (Semester 3)

TOTAL MARKS: 100
TOTAL TIME: 3 HOURS
(1) Question 1 is compulsory.
(2) Attempt any four from the remaining questions.
(3) Assume data wherever required.
(4) Figures to the right indicate full marks.
1 (a) What is an ADT? Briefly explain the categories that classify the functions of a data type. Write an ADT for natural number.(10 marks) 1 (b) What is time complexity? Determine the time complexity of an iterative and recursive functions that adds n elements of the array using tabular method.(10 marks) 2 (a) Develop a structure to represent planets in the solar system. Each planet has fields for the planets name, its distance from the sum in miles and the number of moons it has. Write a program to read the data for each planet and store. Also print the name of the planet that has less distance from the sun.(8 marks) 2 (b) What is a polynomial? What is the degree of the polynomial? Write a function to add two polynomials?(8 marks) 2 (c) For the given sparse matrix A and its transpose, give the triplet representation. A is the given sparse matrix and B will be its transpose.
[ a=egin{bmatrix}15 &0 &0 &22 &0 &-15 \0 &11 &3 &0 &0 &0 \0 &0 &0 &-6 &0 &0 \0 &0 &0 &0 &0 &0 \91 &0 &0 &0 &0 &0 \0 &0 &-28 &0 &0 &0 end{bmatrix} ]

3 (a) Define stack. Implement push and pop functions for stack using arrays.(8 marks) 3 (b) Implement addq and deleteq functions for the circular queue.(6 marks) 3 (c) Write the postfix form of the following expressions
i) (a+b)d+e/(f+ab)+c
ii) ((a/(b-c+d))(e-a)c)
iii) a/b-c+de-ac
(6 marks)
4 (a) Write the different polynomial representation, with an example.(6 marks) 4 (b) For the given sparse matrix write the diagrammatic linked list representation?
[ A=egin{bmatrix} 5&0 &0 &0 \3 &0 &0 &1 \0 &0 &0 &0 \ 8&0 &0 &2 \0 &0 &7 &0 end{bmatrix} ]
(6 marks)
4 (c) Define equivalence class. Write the linked list representation for the twelve polygons numbered 0 through 11 using the following pairs overlap?

i) Selection trees
ii) Forests and its traversals.
(8 marks)
6 (b) Describe the binary search tree with an example. Write a recursive function to search for a key value in a binary search tree.(8 marks) 6 (c) Write the adjacency matrix and adjacency list of the following graph. (4 marks) 7 (a) Briefly explain the following, with an example:
