- Linear Queue, Circular Queue, Priority Queue, Queue Applications
Linear Queue, Circular Queue, Priority Queue, Queue Applications
Define circular queue. How queue differ from stack. Write a program to implement linear queue.[10]
--- A circular queue is a linear data structure that arranges data elements in a circular pattern, where the last element is connected back to the first element. It overcomes the major drawback of a linear queue (wastage of memory space). In a circular queu...
Full solved answer →What is linear queue? Why do we need circular queue? Explain. [5]
A linear queue is a linear data structure that follows the FIFO (First In First Out) principle, where: - Elements are inserted from the REAR end - Elements are deleted from the FRONT end In an array-based linear queue, two pointers are maintained: - FRONT: ...
Full solved answer →Define queue. Explain about enqueue and dequeue operation in circular queue. [5]
A queue is a linear data structure that follows the FIFO (First In First Out) principle, meaning the element inserted first is the one deleted first. Elements are inserted at the rear end and deleted from the front end. Common operations on a queue include:...
Full solved answer →Write short notes on: a. Priority Queue b. Breadth First traversal of a graph [5]
--- A priority queue is a collection of elements in which each element has been assigned a priority value, and the order of deletion and processing is governed by the following rules: 1. An element of higher priority is processed before any element of lower...
Full solved answer →What is priority queue? Why do you need this type of queue? [5]
A priority queue is a special type of queue in which each element is assigned a priority value, and elements are processed (removed) according to their priority rather than their order of insertion (i.e., not strictly FIFO). - In an ascending priority queue...
Full solved answer →Basic Concept of Queue, Queue as an ADT, Primitive Operations in Queue
Explain queue as an ADT. Write a program to implement linear queue. Compare linear queue with circular queue.[10]
--- A Queue is a linear data structure that follows the FIFO (First In First Out) principle, meaning the element inserted first is the one removed first. It is analogous to a real-life queue (e.g., people standing in a line). A Queue ADT defines a data stru...
Full solved answer →Define Queue. Write are different applications of queue? Explain queue operations with example.[10]
A Queue is a linear data structure that follows the FIFO (First In First Out) principle, meaning the element inserted first is the element removed first. It is an ordered collection of elements in which insertion takes place at one end called the REAR and d...
Full solved answer →Explain queue as an ADT. [5]
A queue is an ordered collection of items from which items may be deleted at one end (called the front) and into which items may be inserted at the other end (called the rear). A queue follows the FIFO (First-In-First-Out) principle, meaning the first eleme...
