10 Questions
Explain the concept of height of a tree in binary trees.
The height of a tree is the length of the longest root-to-leaf path in it.
What is the effect of the choice of pivot element on the efficiency of the Quick sort algorithm?
The choice of pivot element significantly affects the efficiency of the Quick sort algorithm.
Describe how to delete a node in a binary search tree with an example.
To delete a node in a binary search tree, we need to consider three cases: no child, one child, and two children.
Explain the concept of a circular queue.
A circular queue is a data structure that uses a single, fixed-size array to implement a queue, where the rear of the queue is connected to the front.
What is the purpose of hashing and how is it implemented?
Hashing is used to map data of arbitrary size to fixed-size values, typically for faster data retrieval. It is implemented using hash functions.
What is the advantage of a doubly linked list over a single linked list?
Doubly linked lists allow traversal in both directions, while single linked lists only allow forward traversal.
What is the limitation of a queue?
The limitation of a queue is that it has a fixed size, and once the queue is full, it cannot accommodate more elements.
When would a doubly linked list be more advantageous than a single linked list?
A doubly linked list is more advantageous when frequent insertions and deletions are required in both forward and backward directions.
What are the Overflow and Underflow conditions in a stack when using an array?
Overflow: Occurs when trying to push an element onto a full stack. Underflow: Occurs when trying to pop an element from an empty stack.
Differentiate between a stack and a queue.
A stack follows Last In First Out (LIFO) principle, while a queue follows First In First Out (FIFO) principle.
Test your knowledge on data structures and algorithms with questions on Quick sort complexity, doubly linked list insertion, binary tree nodes, Java Stack PUSH operation, and constructing an expression tree. Explore circular queue conditions when implemented using arrays.
