- Create a stack S of ten elements. Take a number x from the user and delete the elements smaller than or equal to X from the stack.Example: Suppose your initial stack is S where you pushed 10 elements as below- Top {9, 3, 4, 15, 20, 1, 6, 4, 9, 10} Bottom4. X is taken as input and X= 6. Then pop out and remove the elements smaller than or equal to X. Finally, the stack will look like-Top {9, 15, 20, 9, 10} BottomYou can use only one additional queue to solve this problem.In c++ pleaseCreate a stack S of ten elements. Take a number x from the user and delete the elements smaller than or equal to X from the stack.

- A SpecialStackTM is a stack modified to support the following two operations: PUSHCLEAR(v) successively pops consecutive items from the top of the stack that are less than u, then pushes v onto the stack. POP() deletes the item at the top of the stack. Assume these operations are implemented using a singly-linked list. PUSHCLEAR(v) iter- ates through the linked list to pop the applicable items and then adds v to the beginning. POP() deletes the first item. (a) Describe the ordering of values on the stack. (b) Explain how a single call to PUSHCLEAR(V) could take (n) time. (c) If we assume that every operation takes linear time, we get a naive bound of O(n²) on the total runtime. But this doesn't consider the fact that these expensive operations happen infrequently so let's analyze it more closely. Show that any sequence of n operations takes O(n) time. -The Nth Fibonacci number is defined as the sum of the two previous Fibonacci numbers where the 0th and 1st Fibonacci numbers are defined as 1. What is the maximum size of the stack when this function is called with the argument 5? What is the maximum size of stack when the function is called with n when n >= 4 (expression in term of n) int Fibonacci( int n ) { return (n <= 1) ? 1 : Fibonacci( n - 1 ) + Fibonacci( n - 2 ); }Given a stack, switch_pairs function takes a stack as a parameter and thatswitches successive pairs of numbers starting at the bottom of the stack.For example, if the stack initially stores these values:bottom [3, 8, 17, 9, 1, 10] topYour function should switch the first pair (3, 8),the second pair (17, 9), ...:bottom [8, 3, 9, 17, 10, 1] topif there are an odd number of values in the stack, the value at the top of thestack is not moved: For example:bottom [3, 8, 17, 9, 1] topIt would again switch pairs of values, but the value at thetop of the stack (1)would not be movedbottom [8, 3, 9, 17, 1] topNote: There are 2 solutions:first_switch_pairs: it uses a single stack as auxiliary storagesecond_switch_pairs: it uses a single queue as auxiliary storage""".
- 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.Imagine a stack of dishes, literally. The stack may collapse if it becomes too tall.Therefore, when the prior stack above a certain threshold in real life, we probably start a new stack. Create a data structure called SetOfStacks to resemble this. When a stack's capacity is reached, a new stack should be created and added to the SetOfStacks. SetOfStacks. SetOfStacks with push(). In other words, pop() should return the same values as it would if there were only one stack. It should operate exactly like a single stack.TAKE ACTIONCreate a function called popAt(int index) that does a pop operation on a certain substack.# cannot contain syntax error # stack class class Stack:def __init__(self, iL=[]):self.aList = iL[:] def push(self, newElem:int):"""push a new element on top"""self.aList.append(newElem) def pop(self)->int:"""return top item"""return self.aList.pop() def empty(self):"""Is the stack empty?"""return self.aList == [] def __repr__(self):return repr(self.aList) # use only the above stack methods to define a function to# delete an item x from a stack, (only one x (the upper one) is to be deleted)# keep the order of the remaining items in the stack unchanged# can change orginal stack# return a new stack def delx(sk:Stack, x:'item')-> Stack: #Code goes here if __name__ == "__main__": #Testing code here
- There is one stacks and one queue q and then following operations are performed upon these two. Push A, enqueue B, push C, pop, pop, enqueue D, push E, dequeue, enqueue F .What is the total number of elements, which are left in the queue and stack in the end.Select true or false for the statements below. Explain your answers if you like to receive partial credit 4) Given a stack implemented as a standard linked list (only a head pointer) with O(1)push and O(1) pop, and the following functions are performed in sequence:Push(“Charmander”), Push(“Squirtle”), Push(“Bulbasaur”), Pop(), Push(“Larvitar”),Push(“Eevee”), Pop(), Pop()Which of the following is true after all the functions are executed?a. Charmander and Squirtle will be the only elements left on the stackb. The head node will be pointing to Charmanderc. If you Push(“Pikachu”), it will be the last node of the linked listWrite a structure to represent a Node in a singly linked-list-based stack similar to the onediscussed in class. Your stack will store integer values. Your program will read a series of integers(until the user enters a non-integer) and store them in a stack, then print them in the reverse order;You will write three functions to assist with this task: push, printStack, and deleteStack.The function push takes a number and a Node and adds the number to the head (top) of thestack by creating a new Node (using malloc) and returning a pointer to this Node. This new nodeis now the top of your stack.The function printStack will need to iterate through your stack and print each one (5 spacesper number, left-aligned), with a new line following the nal number. You will need a pointer thatyou update to the next Node each time you print one. Since you add new items to the top of thestack, the newest elements will be printed rst, giving the reverse-order behavior requested.The function deleteStack…
