- A drop-out stack is a data structure that acts just like a stack except that if the stack size is n, and the n + 1 element is pushed, the first element is lost. Using an array, create a drop-out stack. (Hint: A circular array implementation would be appropriate.)In which scenarios would you prefer to use an array over a linked list, and vice versa?detemine if the follow statement are true or False and why? screenshots show the ArrayBoundedStack class and StackUnderflowException code If N represents the number of elements on the stack, then the push method of the ArrayBoundedStack class is O(N). While processing this expression ( } ( ) ( ) { { { } [ ] } } ) the highest number of elements on our stack at any one time is 1. If N represents the maximum possible number of elements on the stack, then the ArrayBasedStack constructor is O(N). The following expression is balanced: ( ( ( [ ) ] ) ) Our StackUnderflowException code essentially consists of two simple constructors and "packages" and "extends" statements and nothing else.
- The CopyTo method copies the contents of a stack into an array. The arraymust be of type Object since that is the data type of all stack objects. Themethod takes two arguments: an array and the starting array index to beginplacing stack elements. The elements are copied in LIFO order, as if they werepopped from the stack. write a short code fragment demonstrating a CopyTomethod call:Stack stores elements in an ordered list and allows insertions and deletions at one end. The elements in this stack are stored in an array. If the array is full, the bottom item is dropped from the stack. In practice, this would be equivalent to overwriting that entry in the array. And if top method is called then it should return the element that was entered recently.A data structure known as a drop-out stack functions exactly like a stack, with the exception that if the stack size is n, the first element is lost when the n + 1 element is pushed. Use an array to implement a drop-out stack. (Hint: It would make sense to implement a circular array.)
- In c++ please explain the code Q1. Given a 'key', delete the first occurrence of this key in the linked list. Iterative Method: To delete a node from the linked list, we need to do the following steps. 1) Find the previous node of the node to be deleted. 2) Change the next of the previous node. 3) Free memory for the node to be deleted.Describe the differences between following Structure and when is the right time to use it Array and ArrayList ArrayList and LinkedList Stack, Queue, ListTask:implement a function that reverses a list of elements by pushing them onto a stack in one order and writing them back to the list in reversed order P.S:Answer must be in python
- Use stack concepts Q # 3-#5 -> https://www.loc-cs.org/~c Essay Questions (20% each)- continue 3. What is the advantage of using ArrayList over LinkedList? 4. How much time do you need to add an element at the end of an ArrayList if the size of an ArrayList is n? a. 0(1) b. 0(n) Describe the reason of your choice. 5. How much time do you need to add an element at the beginning of an ArrayList if the size of an ArrayList is n? a. 0(1) b. 0(n) Describe the reason of your choice. SubmitThe implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.IN PYTHON Linked Lists Consider the implementation of the Linked list class, implement the following functions as part of the class: index(item) returns the position of item in the list. It needs the item and returns the index. Assume the item is in the list. pop() removes and returns the last item in the list. It needs nothing and returns an item. Assume the list has at least one item. pop_pos(pos) removes and returns the item at position pos. It needs the position and returns the item. Assume the item is in the list. a function that counts the number of times an item occurs in the linked list a function that would delete the replicate items in the linked list (i.e. leave one occurrence only of each item in the linked list) Your main function should do the following: Generate 15 random integer numbers in the range from 1 to 5. Insert each number (Item in a node) in the appropriate position in a linked list, so you will have a sorted linked list in ascending order. Display the…
