Furthermore, a binary tree can also have 1 or 2 nodes. Question It takes one element at time and finds it appropriate location in sorted sub-list and insert there. Shell sort divides the list into smaller sublist based on some gap variable and then each sub-list is sorted using insertion sort. Which of the following statement is true?

Prefix Notation: Sorting is not possible by using which of the following methods? Insertion, Selection, Exchange, Deletion. Sorting is not possible in Deletion.

Using insertion we can perform insertion sort, using selection we can perform selection sort, using exchange we can perform the bubble sort and other similar sorting methods. But no sorting method can be done just using deletion. In tree construction which is the suitable efficient data structure?

Array, Linked list, Stack, Queue. Explain What is the type of the algorithm used in solving the 8 Queens problem? Explain What is the bucket size, when the overlapping and collision occur at same time? If there is only one entry possible in the bucket, when the collision occurs, there is no way to accommodate the colliding value. This results in the overlapping of values. Classify the Hashing Functions based on the various methods by which the key value is found.

Explain What are the types of Collision Resolution Techniques and the methods used in each of the type? Open addressing closed hashing , The methods used include: Overflow block. Closed addressing open hashing , The methods used include: Linked list, Binary tree.
