LinkedQueue and CircularArrayQueue Implementation Guide
What methods need to be implemented for LinkedQueue and CircularArrayQueue classes?
Identify the methods that need to be completed for both LinkedQueue and CircularArrayQueue classes.
Answer:
1. To complete the implementation of the Linked Queue class, you will need to add the following methods:
- First method: This method should return the element at the front of the queue without removing it.
- IsEmpty method: This method should return a boolean value indicating whether the queue is empty.
- Size method: This method should return the number of elements in the queue.
- ToString method: This method should return a string representation of all the elements in the queue.
2. To complete the implementation of the CircularArrayQueue class, you will need to add all of the following methods:
- Enqueue method: This method should add an element to the back of the queue.
- Dequeue method: This method should remove the element at the front of the queue and return it.
- First method: This method should return the element at the front of the queue without removing it.
- IsEmpty method: This method should return a boolean value indicating whether the queue is empty.
- Size method: This method should return the number of elements in the queue.
- ToString method: This method should return a string representation of all the elements in the queue.
Implementation Details:
For the LinkedQueue class, you will need to implement each method as described:
- The First method should simply return the element at the front of the queue, without altering the queue itself.
- The IsEmpty method should check if the queue is empty and return true or false accordingly.
- The Size method should count the number of elements in the queue and return that value.
- The ToString method should provide a string representation of all elements in the queue, which can be achieved with a loop to concatenate them into a string.
For the CircularArrayQueue class, the methods described should be implemented as follows:
- The Enqueue method should add an element to the back of the queue, adjusting the circular array accordingly.
- The Dequeue method should remove and return the element at the front of the queue, updating the array structure as needed.
- The First method should simply return the element at the front of the queue.
- The IsEmpty method should determine if the queue is empty and return true or false.
- The Size method should calculate the number of elements in the queue and return that count.
- The ToString method should create a string representation of all elements in the queue, achieved through iterating and concatenating the elements.
By following these implementation details closely, you can ensure that your LinkedQueue and CircularArrayQueue classes are functioning correctly and efficiently.
