## What is the difference between queue and stack Mcq?

queues use two ends of the structure; stacks use only one.

## What is difference between stack array and queue?

Stack has a dynamic and fixed size. Queue can contain elements of different data type. Array contains elements of same data type. The stack can contain elements of the different data types.

## Which is better stack or queue?

Use a queue when you want to get things out in the order that you put them in. Use a stack when you want to get things out in the reverse order than you put them in. Use a list when you want to get anything out, regardless of when you put them in (and when you don’t want them to automatically be removed).

## What is difference between stack and Queue?

Stack and Queue both are the non-primitive data structures. The main differences between stack and queue are that stack uses LIFO (last in first out) method to access and add data elements whereas Queue uses FIFO (First in first out) method to access and add data elements.

## Does stack and Queue require dynamic memory?

Stacks require dynamic memory, but queues do not. Queues use two ends of the structure; stacks use only one.

## Which one of the following is an application of Queue data structure Mcq?

The option b, i.e., data is transferred asynchronously is a application of the Queue data structure. Here asynchronously means that the data received at the different rate as sent.

## What is Queue MCQ?

Explanation: Linear list of elements in which deletion is done at front side and insertion at rear side is called Queue. In stack we will delete the last entered element first. Explanation: Circular Queue is also called as Ring Buffer.

## What is difference between array and stack?

Stack is a sequential collection of objects arranged in a particular order so that objects can be inserted and removed from one end only, which is from the top of the stack. An array, on the other hand, is a random access data structure used to store large number of data values to reduce the complexity of the program.

## What is difference between queue and stack?

A queue is a container of objects (a linear collection) that are inserted and removed according to the first-in first-out (FIFO) principle. The difference between stacks and queues is in removing. In a stack we remove the item the most recently added; in a queue, we remove the item the least recently added.

## What is the difference between queue and ArrayList?

The difference is that for a Queue, you are guaranteed to pull elements out in FIFO order. For an ArrayList, you have no idea what order the elements were added. Depending on how you use it, you could enforce FIFO ordering on an ArrayList.

## Is a stack faster than queue?

While queue and stack aren’t wildly different in performance, they obviously induce a different node-visiting order. One of them may give a more cache-friendly order than the other, depending on how your nodes are laid out in memory.

## How is dynamic stack and queue implemented?

Dynamic Stack

• push() : We use this method to insert element in stack.
• pop() : We use this method to delete element from the stack.
• display() : This method is used to print the elements of stack.
• peek(): This method gives the element present on top of the stack.

## Which one of following is an application of queue data structure?

1) When a resource is shared among multiple consumers. Examples include CPU scheduling, Disk Scheduling. 2) When data is transferred asynchronously (data not necessarily received at same rate as sent) between two processes.

## Which of the following is true about queue data structure Mcq?

This set of Data Structure Multiple Choice Questions Answers (MCQs) focuses on Queue Operations. Explanation: Linear list of elements in which deletion is done at front side and insertion at rear side is called Queue. In stack we will delete the last entered element first. Queue uses FIFO principle.

## Which of the following is an application of data structure?

Data structures such as linked lists can enable core operating systems resources and services to perform functions like file directory management, memory allocation, and processing scheduling queues.

## Which one of the following is an application of stack and queue data structure respectively?

We can implement a stack and queue using both array and linked list. Stack Applications: During Function Calls and Recursive Algorithms, Expression Evaluation, Undo feature in computer keyboard, Converting an Infix to Postfix, During Depth First Search (DFS) and Backtracking Algorithms etc.

## What is queue short answer?

A Queue is an ordered collection of items from which items may be deleted at one end called the front of the queue and into which tems may be inserted at the other end called rear of the queue. Queue is called as First in-First-Out(FIFO)

## What is queue in data structure in MCQS?

Explanation: Linear list of elements in which deletion is done at front side and insertion at rear side is called Queue. In stack we will delete the last entered element first.
