Bulgarian solitaire def bulgarian_solitaire(piles, k): You are given a row of piles of pebbles, all identical, and a positive integer k so that the total number of pebbles in these piles equals k*(k+1)//2, the arithmetic sum formula that equals the sum of positive integers from 1 to k. Almost as if intended as a metaphor for the bleak daily life behind the Iron Curtain, all pebbles are identical and you don't have any choice in your moves. Each move picks up one pebble from each pile (even if doing so makes that pile vanish), and creates a new pile from the resulting handful. For example, starting with[7, 4, 2, 1, 1], the first move turns this into [6, 3, 1, 5]. The next move turns that into [5, 2, 4, 4], which then turns into the five-pile configuration [4, 1, 3, 3, 4], and so on. This function should count how many moves are needed to convert the given initial piles into the goal state where each number from 1 to k appears as the size of exactly one pile, and return that count. These…
(Evaluate expression) Modify Listing 20.12, EvaluateExpression.java, to addoperators ^ for exponent and % for remainder. For example, 3 ^ 2 is 9 and 3% 2 is 1. The ^ operator has the highest precedence and the % operator has thesame precedence as the * and / operators. Your program should prompt theuser to enter an expression. Here is a sample run of the program: Enter an expression: (5 * 2 ^ 3 + 2 * 3 % 2) * 4(5 * 2 ^ 3 + 2 * 3 % 2) * 4 = 160 Here is the Listing 20.12 to modify: import java.util.Stack; public class EvaluateExpression { public static void main(String[] args) { // Check number of arguments passed if (args.length != 1) { System.out.println( "Usage: java EvaluateExpression \"expression\""); System.exit(1); } try { System.out.println(evaluateExpression(args[0])); } catch (Exception ex) { System.out.println("Wrong expression: " + args[0]); } } /** Evaluate an expression */ public static int evaluateExpression(String expression) { // Create operandStack to store operands…

AppleJuice is a superclass that contains an instance of Apple class and an instance of Water.E. Water is a composite class that contains an instance of Juice.
HangmanAA.java For this program, you will create the game Hangman. (If you are unsure of how to play Hangman, Google it.) The game will start by asking player 1 for a word or phrase (can be multiple words). Then player 1 will be asked how many missed guesses are allowed by player 2. Once this information is received, player 2 will take over. (Have the program print many blank lines of space so that player 2 can’t see what player 1 entered.) The instructions should be displayed for player 2 as well as the number of misses they’re allowed to make before they lose the game. The screen should also output dashes or underscores to represent each letter of player 1’s secret word/phrase. Player 2 should guess one letter at a time. Case should not matter. Typing x or X should give the same result. If that letter is present in the mystery phrase, then it should be displayed. (It will replace the dash/underscore in that spot. Spaces, punctuation, and all other non-alphabetic characters should…
Parking Charges Program in java Write a program that works out the amount a person has to pay for parking in a car park in a tourist town. If they say they are disabled, they are told it is free. Otherwise they enter the number of hours as a whole number (1-8) that they wish to park as well as whether they have an “I live locally” badge or are an old age pensioner both of which leads to a discount. The program tells them the cost to park. The calculation is done in this program as follows. If they are disabled it is free. Otherwise ... Take number of hours they wish to park and give a basic charge: • • • • 1 hour: 3.00 pounds 2-4 hours: 4.00 pounds 5-6 hours: 4.50 pounds 7-8 hours: 5.50 pounds Next modify the resulting charge based on whether they are local or not: • If local: subtract 1 pound If OAP: subtract 2 poundsYour program MUST include methods including ones that - asks for the hours and returns the basic charge. - asks whether they live locally /…
Question 2: Ben number (In Java)Ben had difficulty coming out with an assignment question, then he created an odd number called Ben number, which is the sum of a Ben series. Let x be the starting number and y be the bout number, in the Ben series, the x should double the value when it is an even number. In contrast, the number should be subtracted by 1 when x is an odd number. Both x and y should be greater than 0.Example of a Ben series, Assume the x = 3, and y = 5, then the series should be [3, 2, 4, 8,16]. Then the Ben number should be 33 because of 3+2+4+18+16.Thus, given the method benNumber(m,n), for all m, n > 0benNumber(2,5) should return 62 because 2+4+8+16+32 = 62benNumber(3,8) should return 257 because 3+2+4+8+16+32+64+128 = 257benNumber(1,1) should return 1Note that you can only use recursion to solve Q1 and Q2, and you cannot use any loop. You are free to add helper methods, but you are not allowed to change the method header.
(PYTHON) A nutritionist who works for a fitness club helps members by evaluating their diets. As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consumed in a day. Then, she calculates the number of calories that result from the fat, using the following formula: calories from fat = fat grams x 3.9 Next, she calculates the number of calories that result from the carbohydrates, using the following formula: calories from carbs = carb grams x 4 The nutritionist asks you to write a program on *PYTHON* that will make these calculations.
5: CheckLetter.cpp) Write a program that adds a checkletter to an eight-digit number. The check letter should becomputed as follows: Break the number up into 4 two-digitnumbers. Add the four numbers together. Find theremainder after division by 26. The check letter is the letterin the alphabet that corresponds to the number justcomputed. (A=0, B=1, C=2, etc.) Print the original numberfollowed by the check letter. Use at least one ffunction thatreturns a value when you write this program.
Order check Write a program OrderCheck.java that takes four int command-line arguments w, x, y, and z. Define a boolean variable whose value is true if the four values are either in strictly ascending order (w < x < y < z) or strictly descending order (w > x > y > z), and false otherwise. Then, display the boolean variable value.
Change the calendar printing program so it starts the week on a Sunday. Also make it print a newline at the end (but only one). This program had to utilize the code from page 61 and make the necessary changes for printing it. The code itself would display the calendar and you would not have to use the println function as you would have to do that for every single month and year. The program would grab the month a year you selected and display it. import java.time.DayOfWeek;import java.time.LocalDate; public class Calendar { public static void main(String[] args) {// TODO Auto-generated method stubint month = 0;int year = 0;LocalDate date= LocalDate.of(year, month, 1);while (date.getMonthValue() == month) {System.out.print(date.getDayOfMonth());date = date.plusDays(1);}DayOfWeek weekday = date.getDayOfWeek();int value = weekday.getValue();for (int i = 1; i<value; i++);System.out.print(" ");int value1 = date.getDayOfWeek().getValue(); import calendar;y = int(input("Input the years…
