#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

If the number is odd and divisible by 3, it is added into the queue; otherwise the top element, if any, of the stack is removed and the square of the number is added onto the stack. After processing these numbers, what is stored in stack and queue?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.
- 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 ; } }Assess the stack's performance when left alone.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.
