- TOPICS: LIST/STACK/QUEUE Write a complete Java program about Appointment schedule(anything). Your program must implements the linked list The program should have the following basic operations of list, which are: a) Add first, in between and last b) Delete first, in between and last c) Display all data The program should be an interactive program that allow user to choose type of operation.Code with comments and output screenshot is must for an Upvote Create a Java function that uses a stack and no arithmetic to compare the number of 0's and 1's in a string. If # of 0's is greater, return -1. If # of 1's is greater, return 1. If equal, return 0.3- Write a program that randomly generates 10 numbers (between 1 and 8), inserts into queue and then finds how many distinct elements exist in the queue. Example 1: Example 2: Queue: 2 40 3 3 2 18 4 18 18 3 Queue: 1 1 4 33 16 16 4 16 4 Output: 5 Output: 4 Notes: • You must use ONLY queue data structure. Don't use other different data structures like string or normal (pure) array or stack or array list. • Don't write any other method in the Qeueu class. All methods must be written in the main program.
- 2. Write an application utilizing JAVA-ready Stack class and perform the following. Create a new instance of the Stack of type double. Use a loop to get 5 input from the user and insert into the stack created. The inputs are 3.4, 10.1, 10.3, 11.5, 3.5. Write a statement to display the content of the stack. Perform pop() all elements and display on the screen if the number is greater than 5.0. Use the output sample given to guide your code. Sample output: [3.4, 10.1, 10.3, 11.5, 3.5] 11.5 10.3 10.1C# 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.Write a program and fill a queue with random numbers between 0 and 100. The size of thequeue is assumed to be 15. After filling the array with random numbers, display the elements in the queue and remove the elements of the queue and store these numbers according to the following criteria.If the number in the queue is less than 50, remove it from the queue and store it inside queue 2.Else, remove the number and store these values inside queue 3.Display all three queues on the screen.
- Try a spatuladef pancake_scramble(text):Analogous to flipping a stack of pancakes by sticking a spatula inside the stack and flipping over the stack of pancakes resting on top of that spatula, a pancake flip of order k performed for the text string reverses the prefix of first k characters and keeps the rest of the string as it were. For example, the pancake flip of order 2 performed on the string 'ilkka' would produce the string 'likka'. The pancake flip of order 3 performed on the same string would produce 'klika'.A pancake scramble, as defined in the excellent Wolfram Challenges programming problems site, consists of the sequence of pancake flips of order 2, 3, ... , n performed in this exact sequence for the given n-character text string. For example, the pancake scramble done to the string 'ilkka' would step through the intermediate results 'likka', 'kilka', 'klika' and 'akilk'. This function should compute and return the pancake scramble of its parameter text string. text…Compulsory Task Follow these steps: ● For this task, you are required to refactor the badly written program RPN.java. This program is a Reverse-Polish Notation calculator which uses a stack. A Reverse-Polish Notation calculator is a calculator that will calculate equations where the operator follows the operands. Therefore, instead of inputting an equation as “1 + 2”, a Reverse-Polish Notation calculator would take the following input “ 1 2 +”. A stack is a data structure in which items are added to the top of the stack and removed from the top of the stack. It is therefore known as a last-in, first-out (LIFO) data structure. Stack terminology: ○ Push — is an operation that adds an item to the top of a stack. ○ Pop — is an operation that removes an item from the top of a stack. The pseudocode for this program is: ○ Get an equation (e.g. 2 3 +) from the user as input. ○ Loop through the string value input by the user. ■ When you encounter a number (remember that numbers can include…Consider the following statements: linkedStackType<int> stack; linkedQueueType<int> queue; int num; Suppose the input is 28 30 15 11 10 -9 21 8 -3 33 17 14 Write a C++ code that processes these numbers as follows: If the number is an even number, it is pushed onto the stack. 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?
- Task:implement a function that reverses a list of elements by pushing them onto a stack in one order and writing them back to the list in reversed order P.S:Answer must be in python// the language is c++, please code with common for better understanding, and after your code finished take a screenshot of the execution. Write a C++ program to simulate a stack using an array. You should create an index (the stack pointer) to point into the stack. Initialize it to 0. The stack should grow to location [1], [2], [3], etc. Write a "push (int)" function to push an int onto the top of the stack. Also, write an "int pop" instruction to pop the data that is stored on the top of the stack. The pop instruction must return the popped data. The push and pop instructions should increment and decrement the stack pointer appropriately. Your source should contain calls to your functions demonstrating that it works. Note, that you should do several pushes and several pops to show that data is correctly stored on the stack. You can do this by showing sample runs. Cut and paste the results of the runs into a separate documentCreate a queue, size of queue will be dependent on the user. Insert the numbers in the queue till the queue reaches the size. Create a menu and perform the following function on that queue. This is all done by using oop in C++. Enqueue: Add an element to the end of the queue Dequeue: Remove an element from the front of the queue IsEmpty: Check if the queue is empty IsFull: Check if the queue is full Peek: Get the value of the front of the queue without removing it
