- 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""".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} Bottom X is taken as input and X= 6. Then pop out and remove the elements greater than or equal to X. Finally, the stack will look like- Top {3, 4, 1, 4} Bottom In c++ PleaseCode in C One of the applications of a stack is to backtrack - that is, to retrace its steps. As an example, imagine we want to read a list of items, and each time we read a negative number we must backtrack and print the five numbers that come before the negative number and then discard the negative number. Use a stack to solve this problem. Use a stack and push them into the stack (without printing them) until a negative number is read. At this time, stop reading and pop five items from the stack and print them. If there are fewer than five items in the stack, print an error message and stop the program. After printing the five items, resume reading data and placing them in the stack. When the end of the file is detected, print the message and the items remaining in the stack. Sample Output 1 2 3 4 5 6 7 -1 7 6 5 4 3 9 6 4 3 -2 3 4 6 9 2 -3 Number of items left is less than five! Program is terminating! Project name : Backtrack Filenames: backtrack.h, backtrack.c,…
- Write 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…C# Display the stack with the given information: int topNum; NumberStack stack2 = new NumberStack(5); stack2.Push(5);stack2.Push(7);stack2.Push(12);stack2.Push(3); public void PrintStack() { //Loop through each element of the stack and display it for (int i = size - 1 ; i >= 0; i--) { Console.WriteLine(stack[i]); } }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. -
- 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.

- 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 ); }A stack is very useful in situations when data have to be stored and then retrieved in the —- order. A) same B) reverse C) ascending D) descendingGiven a class Stack with the interface public void push(char n) // pushes n onto stack public char pop() // return the top of the stack, removing element from stack public boolean isEmpty() // return true if stack is empty Write a method public void addStars(Stack<Character> stack) which takes a Stack as input and adds two asterisk (‘*’) at the front and back of all the elements in the stack. The stack must be restored to its original order plus the asterisks. For example, the stack [bottom] a b c d [top] Would become [bottom] ** a b c d ** [top]
