- Consider the following code segment , The variable q is an object of type Queue, the variable s is an object of type Stack. peek method looks at the first element in the queue without removing it. the remove method removes the first element from the queue. add method adds an element to the and of the queue or add an element to the top of the stack. pop method removes an element from the top of the stack What would be the content of the variable q (8 numbers) after we complete the second while loop in the code for (int i = 30; i <= 40; i ++) { if(i % 3 == 0) q.add(i); } while (!q.isEmpty()) { s.add(q.peek()); s.add(q.peek()); q.remove(); } while (!s.isEmpty()) { q.add(s.pop()); }Your job is to implement a Stack using only a Queue(s). That is, you will be responsible for writing the push and pop methods for a Stack but your internal data representation must be a Queue: void push(Queue& queue, int element) int pop(Queue& queue)Add remain code and explanation of whole code. Given a stack, a function is_consecutive takes a stack as a parameter and thatreturns whether or not the stack contains a sequence of consecutive integersstarting from the bottom of the stack (returning true if it does, returningfalse if it does not). For example:bottom [3, 4, 5, 6, 7] topThen the call of is_consecutive(s) should return true.bottom [3, 4, 6, 7] topThen the call of is_consecutive(s) should return false.bottom [3, 2, 1] topThe function should return false due to reverse order. Note: There are 2 solutions:first_is_consecutive: it uses a single stack as auxiliary storagesecond_is_consecutive: it uses a single queue as auxiliary storage"""import collections def first_is_consecutive(stack): storage_stack = [] for i in range(len(stack)): first_value = stack.pop() if len(stack) == 0: # Case odd number of values in stack return True second_value = stack.pop() if first_value -…
- How nodes are defined (struct node (value count left right) #:mutable #:transparent) Write in Racket (traverse n) A traversal of a BST is an algorithm for “visiting” all node in the BST. The traversal must visit each node exactly once. In the case of a linked list, a traversal is trivial since the structure is linear: start at the head, move to the next node, and stop when you reach the tail. In the case of a BST, traversal must account for multiple child nodes and keep track of which subtrees have already been visited and which have not. There are three types of traversal: in-order, pre-order, and post-order. We will only implement in-order. The in-order traversal of a BST has the property that the node values will display in ascending or sorted order. The function can be defined either recursively or iteratively. Recursion is much simpler, so we’ll stick to that. Recursive Algorithm for In-Order Traversal of BST parameter: node n, the root of the tree…The Deque ADT combines characteristics of the Stack and the Queue. The name “Deque" comes from "double-ended queue" and is usually pronounced "deck". Like the Stack and the Queue, a Deque permits elements to be accessed only at the ends. However, a Deque allows items to be added at either end and removed from either end. We can refer to the operations supported by the Deque as enqueueFront, enqueueRear, dequeueFront, and dequeueRear. Note that once you have a Deque, you can use it to implement both the Stack and the Queue. Implement the Deque using a dynamic, linked implementation (15pts) Use your Deque to implement a Stack (15pts). Use your Deque to implement a Queue (15pts). Test your implementation across the 3 data structures to tell the story of your work (10pts).The Priority. Queue ADT As an ADT, a priority queue P supports the following functions: • isPQueueEmpty(): returns true if pqueue is empty otherwise false size(): Return the number of elements in P. empty(): Return true if P is empty and false otherwise. Example: The following table shows a series of operations and their effects on an initially empty priority queue P. Each element consists of an integer. which we assume to be sorted according to the natural ordering of the integers. Note that insert(e): Insert a new element e into P. min(): Return a reference to an element of P with the smallest associated kex value (but do not remove it); an error condition occurs if the priority queue is empty. removeMin): Remove from P the element referenced by min(); an error condition occurs if the priority queue is empty. each call to min returns a reference to an entry in the queue, not the actual value. Although the "Priority Queue" column shows the items in sorted order, the priority queue…
- 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.Radix Sorting Algorithm In C++, implement the radix sorting algorithm using a queue class.Steps: Create a queue filled with 10 random integers between 1000 and 9999. Next, create a list of 10 empty queues (0-9 digit bins), then dequeue each number from the main queue and enqueue them into the correct digit bin. Dequeue the numbers from each digit bin in order and enqueue them back into the main queue. Repeat the process for every digit (tens, hundreds, thousands, etc.) Finally, print the sorted list.A(n) array can be used in an array implementation of a queue to avoid an overflow error at the rear of the queue when the queue is not full.
- O(N) is the order of growth execution time of the enqueue operation when using the ArrayBoundedQueue class, assuming a queue size of N. T or FQuestion 9: Draw internal representation of the queue q for each step of the following code: ArrayBoundedQueue<Integer> q = new ArrayBoundedQueue<Integer>(6); q.enqueue(37); q.enqueue(86); q.enqueue(54); q.enqueue(71); q.dequeue(); q.enqueue(97); q.dequeue();Given the following stack A = {29,18,10,15,20,9,5,13,2,4,15) Create a queue by taking the elements from the top of the stack and adding them to the queue.
