Q 1 - Prefix notation is alsow known as
Answer : D
Explanation
Polish Notation
Q 2 - A circular linked list can be used for
Answer : C
Explanation
Both stack and queue data structure can be represented by circular linked-list.
Q 3 - Minimum number of moves required to solve a Tower of Hanoi puzzle is
Answer : C
Explanation
Minimum number of moves required to solve a Tower of Hanoi puzzle is 2n - 1. Where n is the number of disks. If the number of disks is 3, then minimum number of moves required are 23 - 1 = 7
Q 4 - Which of the following algorithm is not stable?
Answer : B
Explanation
Among the given, only quick sort is not stable that is it may re-arrange the already sorted items.
Q 5 - Graph traversal is different from a tree traversal, because
Answer : C
Explanation
As trees do not have loops, they are easier to traverse.
Q 6 - The number of binary trees with 3 nodes which when traversed in post order gives the sequence A,B,C is ?
Answer : C
Explanation
Five binary trees (of 3 nodes) are possible.
Answer : B
Explanation
Linked lists has search complexity of Ο(n).
Q 8 - Program with highest run-time complexity is
Answer : A
Explanation
Tower of hanoi has the highest run time complexity
Q 9 - Access time of a binary search tree may go worse in terms of time complexity upto
Answer : C
Explanation
At maximum, BST may need to search all n values in the tree in order to access an element, hence, Ο(n).
Q 10 - Project scheduling is an example of
Answer : B
Explanation
Project scheduling is an exmaple of dynamic programming.
