**IBPS SO IT Questions**

A candidate can go through these IBPS SO IT questions.

31.What is a sparse array?

1) Data structure for representing arrays of records

2) Data structure that compactly stores bits

3) An array in which most of the elements have the same value

4)All of the above

5) None of the mentioned

Answer : (3) Basic definition

32.What is the time complexity of pre-order traversal in the iterative fashion?

1)O(1)

2)O(n)

3)O(log n)

4)O(nlogn)

5)O(n*n)

Answer : (2)

33.To obtain a prefix expression, which of the tree traversals is used?

1) Level-order traversal

2) Pre-order traversal

3) Post-order traversal

4) In-order traversal

5)None of these

Answer : (2)

34.Inventors of AVL tree are

1)Adelson-Velsky

2)Landis

3)Both 1 and 2

4)Adel

5)None of these

Answer: (3)AVL tree (named after inventors Adelson-Velsky and Landis) is a self-balancing binary search tree. It was the first such data structure to be invented. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property.

35.Heap exhibits the property of a binary tree?

1) True

2) False

Answer : (1)Yes, Because the leaf nodes are present at height h or h-1, which is a property of complete binary tree.

36.Heap can be used as ________________

1) Priority queue

2) Stack

3) A decreasing order array

4)An increasing order array

5) None of the mentioned

Answer : (1)The property of heap that the value of root must be either greater or less than both of its children makes it work like a priority queue.

37.If several elements are competing for the same bucket in the hash table, what is it called?

1) Diffusion

2) Replication

3) Collision

4)Redundancy

5) None of the mentioned

Answer : (3)

38.What is a hash function?

1) A function has allocated memory to keys

2) A function that computes the location of the key in the array

3) A function that creates an array

4)A function has deallocated memory to keys

5) None of the mentioned

Answer : (2)In a hash table, there are fewer array positions than the keys, so the position of the key in the array has to be computed, this is done using the hash function.

39.A connected planar graph having 6 vertices, 7 edges contains _____________ regions.

1) 15

2) 3

3) 1

4) 11

5)15

Answer : (2)By eulerâ€™s formula the relation between vertices(n), edges(q) and regions(r) is given by n-q+r=2.

40.What is the maximum number of edges in a bipartite graph having 10 vertices?

1) 24

2) 21

3) 25

4) 16

5)15

Answer : (3)Total number of edges would be n*(10-n), differentiating with respect to n, would yield the answer.

So a candidate should start their preparation as early as possible because as an IBPS SO IT Officer one is not only responsible for taking care of software and network system but an IBPS SO IT Officer also has to evaluate new technology,maintain databases for the successful implementation and growth of the bank,whose prosperity is very important for a nation to be developed.
