Data Structure MCQ (Multiple Choice Questions)

Data Structure MCQ 1) For sorting random linked list with the minimum time complexity, which of the following algorithm requires? Merge SortBubbleSelection SortInsertion Sort Show AnswerWorkspace Answer: (A) Explanation: Both Merge sort and Insertion sort can be used...

Red Black Tree

Red Black Tree A red-black tree is referred as self-balancing binary search tree. The tree was invented by Rudolf Bayer in 1972. In red-black, each node stores an extra bit that determines the color of the node in red-black tree either red or black. These colors...

Splay Tree

Splay Tree A splay tree is a self-balanced or self-adjusted binary search tree. We can say, Splay Tree is used in some cases where some elements or data are accessed more frequently over other elements or data. The splay tree self-adjusts after the search, insert, and...

AVL Tree

AVL Tree AVL Tree is referred to as self-balanced or height-balanced binary search tree where the difference between heights of its left subtree and right subtree (Balance Factor) can’t more than one for all nodes covered by a tree. Example: We can say a tree is...

Circular Queue

Circular Queue Circular Queue is special type queue, which follows First in First Out (FIFO) rule and as well as instead of ending queue at the last position, it starts again from the first position after the last position and behaves like circular linear data...

Deque in Data Structure

Deque A deque referred as “Double-Ended Queue”, is a linear collection of data items same like queue data structure. deque has two ends, front end and rear end, deque is the unrestricted type of data structure, data item can be added into it either front or rear and...

Priority Queue in Data Structure

Priority Queue A priority queue is a special kind of queue, in priority queue we give some priority to an element and according to this priority an element can be served in the queue. Generally, the value of element is treated as the priority of an element. Like, the...

Graph Data Structure

A graph is a non-primitive and non-linear data structure. It is a group of (V, E) where V is a set of vertexes, and E is a set of edge. In the graph, a vertex is connected with another vertex, and the connection between two vertexes is called edge. Edge acts as a...

Stack Data Structure

The stack is a non-primitive and linear data structure. It works on the principle of LIFO (Last In First Out). That is, the element that is added to the end is removed first, and the element that is added first is removed at the end. There is only one end to insert...

Merge sort

Merge sort Merge sort is based on the divide & conquer sorting technique. Merge sort is a very efficient sorting algorithm. The divide & conquer technique was introduced by John Newman in 1945. The divide & conquer is a technique in which a complex list of...
