Task Write a program that can dynamically change the font of a text in a label displayed on a stack pane. The text can be displayed in bold and italic at the same time. You can select the font name or font size from combo boxes. The available font names can be obtained using Font getFontNames(). The combo box for the font size is initialized with numbers from 1 to 100. Lab22 Font Name Comic Sans MS Font Size 30 Programming is fun Bold Italic
Create an application that reads a statement from the user and outputs it with the characters of each word reversed. To reverse the letters in each phrase, use a stack.
In this assignment you are going to create an application that reverses a text file and saves it. This application is a single file application so you do not need to think about additional classes; you will simply have a main.cpp file. Your application should accomplish: In main, create a stack. Then, open a text file and read its contents into a stack of characters.. The program should then pop the characters from the stack and save them in another text file. As this is a stack, (LIFO, so last item you put into the stack gets the first one to come out), the new file will be the reverse of the other. So if the text file at first said KHAS, the new file must have SAHK.
public interface StackInterface void push (T element) throws StackoverfloWException; void pop () throws StackUnderflowException; T top () throws StackUnderflowException; boolean isFul1 (); boolean isEmpty(); Show what is written by the following segments of code (see printın on the code), given that iteml, item2, and item3 are int variables, and ali is an object that fits the abstract description of a stack as shown above StackInterface. Assume that you can store and retrieve variables of type int on ali. iteml = 2; item2 = 0; item3 = 6; ali.push (item2); ali.push (item1); ali.push ( iteml+item3); item2 = ali.top ( ); ali.push (item3*item3); ali.push (item2); ali.push (3); iteml = ali.top ( ); ali.pop( ); System.out.println (iteml + " " + item2 + while (!ali.isEmpty( )) + item3); iteml = ali.top( ) ; ali.pop () ; System.out.println (item1) ;
You are given a stack of 10 matches. Players take turns taking matches from the stack. A player can take 1, 3, 5 or 7 matches at a time. The player who takes the last match wins. Which of the following is a losing state? Select one or more: a. 9 b. 4 c. 8 d. 2
You are required to implement expression evaluation. Take input an expression and convert it into postfix and then calculate the result using stack. 00:08 !
1. Use a below-given starter code. Use StackInterface.(h), and ArrayStack.(h,cpp). You will write your own StackDriver.cpp application file. IT'S IN C++Also...If the class that you create is Star, remember that you will declare your stack as follows:ArrayStack<Star> myStarStack;and you will push, pop, and peek Star objects.2. Create your own class definition. I should have at least one attribute, a constructor, and set and get methods for each attribute in your class.NOTE: If your class is offensive your lab will be rejected and you will receive a score of zero. I'm sorry I have to say this but there is a history of this happening and it is not appropriate.3. Write a driver program that exercises the Stack class from the downloaded starter code. Create multiple instances of your own class and demonstrate the stack operations: push, pop, and peek. ( you write your own class that you will put on the stack and you will write a driver that pushes, peeks, and pops your class items…
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:
A. Write a program that will input 10 numbers on the stack and will output how many numbers inside the stacks are positive even numbers and negative odd numbers. *Using Iostream*With Screenshot

Exercise 2: Write a program that reads n values from an input screen and stores them in a list T1, then fills another list T2 with values from T1 where any consecutive duplicated values appears only one time, i.e. removes consecutive duplicated values. If you run your program with the following input data: 4 7 3 3 3 6 14 14 10 5 7 7 7 7 2 2 4 4 4 10. Your output should be as follows: Number of elements in T1: 20 T1: 4 7 3 3 3 6 14 14 10 5 7 7 7 7 2 2 4 4 4 10 Number of elements in T2: 11 T2: 4 7 3 6 14 10 5 7 2 4 10 Your program should have at least these 3 functions: 1. main():displays the original list T1, the number of elements of T2 and list T2 2. readData():reads data from input screen into a list 3. removeConsecutiveDuplicates(): takes a list and remove any consecutive duplicated numbers
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…
