Professor Nitwit obtains a hash number of a given positive integer > 3 as
follows. He subtracts 2 from the number (to get the new number),and multiplies
the new number by 2 to get a term. He repeats this with the new number (to get
newer numbers and terms) until the number becomes 2 or 1. The hash is defined
as the sum of all the terms generated in this process.

example, with the number 5, he multiplies (5-2 =3) by 2 to get the first term
6. He multiplies (3-2=1) by 2 to get the second term 2. As the number has
become 1, he stops. The hash is the sum of the two terms (6+2) or 8.

professor Nitwit is given 3 numbers 4, 9 and 13, what is the sum of the hash
numbers he obtains for the three numbers?

  1. Linked list
  2. Array
  3. Queue
  4. Stack

What is the data type that occupies the least storage in “C”

give the answer in the blank line: __________

Which of the following is true?

  1. Array is a dynamic data structure whose size can be changed while stacks
    are static data structures whose sizes are fixed.
  2. Array elements can be accessed and modified(elements can be added or
    removed) only at the ends of the array while any elements of the stack can be
    accessed or modified randomly through their indices.
  3. An array can have elements of different data types.
  4. Elements of a linked-list can be accessed only sequentially.

Which of the following statements is FALSE?

  1. The time complexity of binary search is O(log n).
  2. A linear search requires a sorted list.
  3. A binary search can operate only on a sorted list.
  4. The time complexity of linear search is O(n).

Eesha wrote a function fact( ) in “C” language to calculate factorial
of a given number and saved the file as fact.c. She forgot to code the main
function to call this fact function. Will she be able to compile this fact.c
without the main() function?

  1. Yes, she can compile provided the compiler option -no strict-checking is
  2. No, she can not compile as the main function is required to compile any
    C program file.
  3. Yes, she can compile as main( ) is not required at compile time.
  4. Yes, she can compile and run as the system will supply default values to
    fact function.

The difference between variable declaration and variable definition is:

  1. Declaration and definition are the same. There is no difference.
  2. A declaration is used for variables and definitions is used for functions.
  3. Declaration associates type to the variable whereas definition
    associates scope to the variable.
  4. Declaration associates type to the variable whereas definition gives the
    value to the variable.

The in order and pre order traversal of a binary tree are db ea fc g and a bd
ec f g, respectively. The post-order traversal of the binary tree is:

Eesha wrote a recursive function that takes the first node in a linked list as
an argument, reverses the list, returning the first Node in the result. The
pseudo code for this function is given below. However, she did not get the
correct result. In which line number did she make a mistake?

give the answer in the blank line: ____________

  public Node reverse(Node first)
if (first == null) return null;
if ( == null) return first;
Node second =;
Node rest = reverse (second); = first; = null;

The longest common subsequence (LCS) problem is the problem of finding the
longest subsequence common to a set of sequences (often just two sequences). A
subsequence is a sequence that can be derived from another sequence by deleting
some or no elements without changing the order of the remaining elements. One
form of implementation of LCS function is given below. The function takes as
input sequences X[1…m] and Y[1…n], computes the length of the Longest
common subsequence between X[1..i] and Y[1..j] for all 1<i<m
and 1<j<n, and stores it in C[i,j]. C[m,n] will contain the
length of the LCS of X and Y.

function LCSLength(X[1..m], Y[1..n])
C = array(0..m, 0..n)
for i:= 0..m
C[i,0] =0
for j := 0..n
C[0,j] = 0d
for i := 1..m
for j := 1..n
if X[i] = Y[j]
C[i,j] := C[i-1, j-1] + 1
C[i,j] := max(C[i, j-1], C[i-1, j])
return C[m, n]

Eesha used the above algorithm to calculate the LCS length between “kitten” and “string”. What was the result she got? Please give the answer in the blank line. ___________
