Write a program for Stack (Array-based or linked list-based) in Python. Test the scenario below with the implementation and with the reasoning of the answer. Make comments with a short description of what is implemented. Include source codes and screen-captured outputs. Stack: Given an empty stack in which the values A, B, C, D, E, F are pushed on the stack in that order but can be popped at any time, give a sequence of push and pop operations which results in pop()ed order of BADECF

Write a program for the implementation of a queue using singly linked list. The elements of the queue should be strings of length at most 20 characters. Print the queue and do the following operations on the created queue : (a) Insert a new element. (b) Delete an element from the queue.
Consider a (literal) plate stack. If the stack becomes too tall, it may collapse.In practise, we would most likely create a new stack when the preceding stack reaches a certain threshold. Create a data structure SetOfStacks that is similar to this. SetOfStacks should be made up of many stacks and should build a new stack when the preceding one reaches its capacity.SetOfStacks. Push() and SetOfStacks are both functions. pop() should operate exactly like a single stack (that is, it should return the same values as if there were just one stack).COMPLETE THE FORMULACreate a popAt(int index) method that executes a pop operation on a given substack.
Implement a nonrecursive version of quicksort basedon a main loop where a subarray is popped from a stack to be partitioned, and the resulting subarrays are pushed onto the stack. Note : Push the larger of the subarrays ontothe stack first, which guarantees that the stack will have at most lg N entries.
The 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.

Write a Java program that: • Defines a linked list data structure to represent a collection of integers. • Populates the linked list with random integers. • Implements three different operations on the linked list: Finding the maximum element Finding the minimum element Calculating the sum of all elements • Tests these operations and ensures their correctness. Provide a big-Oh characterization, in terms of n, of the time complexity for each of the implemented operations on the linked list. Improve the linked list implementation to have a method for removing duplicates in O(N) time complexity.
Write a java function to find minimum moves required for making 2 List<Integer> equal. public int minimumOps(List<Integer> S, List<Integer> T){} The two possible moves are: shift(list) returns a new list after moving the front number to the back—i.e., [1, 2, 3 ,4 ] -----> [2, 3, 4, 1] reverse(list) returns the reverse of the list—i.e., [1, 2, 3, 4] -------> [4, 3, 2, 1] for example: consider S = {1, 2, 3, 4} and T = {2, 1, 4, 3}, we can see that T = shift ( shift( reverse( S ))) S = [1, 2 , 3 ,4] -----> [4, 3, 2, 1] ------>[3, 2, 1, 4] -------->[2, 1, 4, 3] = T = 3 moves total. But this is not the only way to transform S to T. To illustrate, here are some other sequence of operations : T = reverse(shift(shift(S))) T = shift(reverse(shift(S))) T = reverse(shift(shift(reverse(reverse(S)))))) Goal is to find the minimum moves on S list to form T list.

Implement 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 operations
