#include <stack>
using namespace std;
int main()
{
stack<int> s; //declare a stack
for(int i=1;i<=8;i++) //for 8 times
{
int input;
cout << "Enter an element to be pushed: ";
cin >> input; //read input
s.push(input); //push input to stack
}
cout << "Size of stack = " << s.size() << endl; //print size
cout << "Top element = " << http://s.top() << endl; //print top
s.pop(); //remove top element
cout << "Top element after deletion = " << http://s.top() << endl; //print top

- Evaluate the following statement using stack : t = power ( 2,3 ) ; Where power( ) defined as follows : int power ( int b , int h ) { int y ; if ( h == 0 ) return 1 ; else { y = power( b , h-1 ); return b*y ; } }C# Reverse the stack - This procedure will reverse the order of items in the stack. This one may NOT break the rules of the stack. HINTS: Make use of more stacks. Arrays passed as parameters are NOT copies. Remember, this is a procedure, not a function. This would occur in the NumberStack class, not the main class. These are the provided variables: private int [] stack;private int size; Create a method that will reverse the stack when put into the main class.Q1: Write a java application for the stack operations with Linked List. Q2: Write java program to take the order from the customer and display the ordered items and total payment. If customer is entering the wrong name or not following the order to enter the menu it has to display error messages. (Find in the sample code) Sample Output:
- Stacks 1- Write a Python function that takes a user input of a word and returns True if it is a Palindrome and returns False otherwise (Your function should use a Stack data structure). A palindrome is a word that can be read the same backward as forward. Some examples of palindromic words are noon, civic, radar, level, rotor, kayak, reviver, racecar, redder, madam, and refer. 2- Write a Python function that takes a stack of integer numbers and returns the maximum value of the numbers in the stack. The stack should have the same numbers before and after calling the function. 3- Write a main function that tests the functions you wrote in 1 and 2 above and make sure that your code is well documented.First picture: create a complete programming codes about the picture. Use pre-defined for stack. Sencond Picture: Test results or the supposed outcome of the programming. Note: put a comment in every line to describe what is the function of each specific codes, variables, etc.C# Reverse the stack - This procedure will reverse the order of items in the stack.
