Consider the following data and specify which one is Preorder Traversal Sequence, Inorder and Postorder sequences. S1: N, M, P, O, Q S2: N, P, Q, O, M S3: M, N, O, P, Q

Correct Answer: S1 is inorder, S2 is postorder and S3 is preorder
Preorder traversal starts from the root node and postorder and inorder starts from the left child node of the left subtree. The first node of S3 is different and for S1 and S2 it’s the same. Thus, S3 is preorder traversal and the root node is M. Postorder traversal visits the root node at last. S2 has the root node(M) at last that implies S2 is postorder traversal. S1 is inorder traversal as S2 is postorder traversal and S3 is preorder traversal. Therefore, S1 is inorder traversal, S2 is postorder traversal and S3 is preorder traversal.

Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.

Consider the following data. The pre order traversal of a binary tree is A, B, E, C, D. The in order traversal of the same binary tree is B, E, A, D, C. The level order sequence for the binary tree is _________

In preorder traversal of a binary tree the second step is ____________

In postorder traversal of binary tree right subtree is traversed before visiting root.

Find the postorder traversal of the binary tree shown below.

Each item consists of six sentences of a passage. The first and sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences and markyour response accordingly on the Answer Sheet.
S1 :The dawn of the information age opened up great opportunities for the beneficial use of data.
S6 :To some, in this era of Big Data analytics and automated, algorithm-based processing of zettabytes of information, the fear that their personal data may be unprotected may conjure up visions of a dystopian world in which individual liberties are compromised.
P :But it is the conflict between the massive scope for progress provided by digital era and the fear of loss of individual autonomy that is foregrounded in any debates about data protection laws.
Q : It also enhanced the perils of unregulated and arbitrary use of personal data.
R : It is against this backdrop that the White Paper made public to elicit views from the public on the shape and substance of a comprehensive data protection law assumes significances.
S :Unauthorised leaks, hacking and other cyber crimes have rendered databases vulnerable.
The correct sequence should be

What is the speciality about the inorder traversal of a binary search tree?

Does there exist a heap with seven distinct elements so that the Inorder traversal gives the element in sorted order.

Sequence similarity and sequence identity are synonymous for nucleotide sequences and protein sequences as well.

Which of the following traversal in a binary tree is similar to depth first traversal?
