=======================
Java
Consider our array-based unbounded queue implementation. What would be the effect of starting with a capacity of 1? What would be the effect of starting with a capacity of 0?
Due to the benefits that circular arrays provide to queues, the issue arises as to whether or not a circularly linked list would reap the same benefits from the same considerations in C++ data structures. Where is the value in that?

- This is a java data structures question - Given a circular bent array-based queue capable of holding 100 objects. Suppose the queue is initially empty, and then objects are put into the queue at the rate of 10 per minute while meantime they are processed and removed from the queue at the rate of 5 per minute. After 120 elements have been added to the queue, which of the following is true? CIRCLE JUST ONE LETTER FOR THE ANSWER. -> You can’t add 120 elements to an array holding 100 entries. -> There will be 60 elements in the queue, 20 of them at the front of the array where the queue started, and 40 at the other end. -> There will be 60 elements in the queue, 30 of them at the front of the array where the queue started, and 30 at the other end. -> There will be 60 elements in the queue, 40 of them at the front of the array where the queue started, and 20 at the other end.arrow_forwardWrite a C++ program to simulate the working of queues using an array provide the following operation: i) Insert ii) Delete iii) DisplayAssume that the size of the queue is 5.

- design a queue data structure without using any data structure like array in javaarrow_forwardImplement in Python a double-ended queue (deque): A double-ended queue is a data structure (ordered collection of items) similar to a traditional queue. It has two ends, front and end, but it is not restricted to adding or removing items. New items can be added on the front or on the end. Existing items can be removed from either end. The image graphically shows how the structure is. - Implement the requested structure using a single linked list, which implements the following functions: enterFront, enterEnd, removeFront, removeEnd- The data to be entered are animal-type objects; name, type of animal, age- Create a Main function with the available operationsarrow_forwardProblem 1: Consider an array-based queue implementation.

- Write a C program to implement a queue of at most elements using an array of size n. ⦁ At the beginning of your code (outside all subprograms), declare a datatype named `struct Queue`. It must be designed according to the pseudo codes (refer to Figure 2) and the provided main function⦁ Define the subprograms to implement the build, enqueue, and dequeue operations. The meaning of enqueue and dequeue is explained in the pseudocodes in Figure 2. The pseudocodes do not include error checking for underflow and overflow. You are required to extend and implement them to prevent underflow and overflow of the queue. ⦁ Additionally, your code must check for any other potential errors, such as accessing null pointers. Also, add a few comments to your code to explain the behavior of the main and subprograms. Ensure that your build, enqueue, and dequeue operations print informative messages as demonstrated in Figure 3. Ensure you test your code with varying sequences of enqueue and…arrow_forwardExamine the data structure of the queue as well as the operations that are carried out at the most fundamental level.
