Chapter 6, Problem 6.27E
(Eight Queens: Brute-Force Approaches) In this problem you’ll develop several brute-force approaches to solving the Eight Queens problem introduced in Exercise 6.26.
- Solve the Eight Queens problem, using the random brute-force technique developed in Exercise 6.25.
- Use an exhaustive technique (i.e., try all possible combinations of eight queens on the chessboard).
- Why do you suppose the exhaustive brute-force approach may not be appropriate for solving the Eight Queens problem?
- Compare and contrast the random brute-force and exhaustive brute-force approaches in general.

Lucky Pairs
Richie and Raechal are participating in a game called "Lucky pairs" at the Annual Game Fair in their Company. As per the rules of the contest, two members form a team and Richie initially has the number A and Raechal has the number B.There are a total of N turns in the game, and Richie and Raechal alternatively take turns. In each turn, the player's number is multiplied by 2. Richie has the first turn. Suppose after the entire N turns, Richie’s number has become C, and Raechal’s number has become D, the final score of the team will be the sum of the scores (C+D) of both the players after N turns. Write a program to facilitate the quiz organizers to find the final scores of the team. Input and Output Format:The only line of input contains 3 integers A, B, and N.Output a single line that contains the integer that gives the final score of the team which will be the sum of the scores of both the players after N turns.Refer sample input and output for formatting specifications.…
def winning_card(cards, trump=None): Playing cards are again represented as tuples of (rank,suit) as in the cardproblems.pylecture example program. In trick taking games such as whist or bridge, four players each play one card from their hand to the trick, committing to their play in clockwise order starting from the player who plays first into the trick. The winner of the trick is determined by the following rules:1. If one or more cards of the trump suit have been played to the trick, the trick is won by the highest ranking trump card, regardless of the other cards played.2. If no trump cards have been played to the trick, the trick is won by the highest card of the suit of the first card played to the trick. Cards of any other suits, regardless of their rank, are powerless to win that trick.3. Ace is the highest card in each suit.Note that the order in which the cards are played to the trick greatly affects the outcome of that trick, since the first card played in the trick…
Knight's Tour: The Knight's Tour is a mathematical problem involving a knight on a chessboard. The knight is placed on the empty board and, moving according to the rules of chess, must visit each square exactly once. There are several billion solutions to the problem, of which about 122,000,000 have the knight finishing on the same square on which it begins. When this occurs the tour is said to be closed. Your assignment is to write a program that gives a solution to the Knight's Tour problem recursively. You must hand in a solution in C++ AND Java. The name of the C++ file should be "main.cc" and the name of the Java file should be "Main.java". Write C++ only with a file name of main.cc Please run in IDE and check to ensure that there are no errors occuring
Output should look similar to:

- 6.28 LAB: Check if array is sorted Use java Programming Write the inOrder() method, which has an array of integers as a parameter, and returns true if the numbers are sorted (in order from low to high) or false otherwise. The program outputs "In order" if the array is sorted, or "Not in order" if the array is not sorted. Ex: If the array passed to the inOrder() method is [5, 6, 7, 8, 3], then the method returns false and the program outputs: Not in order Ex: If the array passed to the inOrder() method is [5, 6, 7, 8 , 10], then the method returns true and the program outputs: In order public class LabProgram {public static boolean inOrder(int [] nums) {/* Type your code here. */ }public static void main(String[] args) {// Test out-of-order example.int [] nums1 = {5, 6, 7, 8, 3};if(inOrder(nums1)){System.out.println("In order");}else{System.out.println("Not in order");}// Test in-order example.int [] nums2 = {5, 6, 7, 8, 10};if(inOrder(nums2)){System.out.println("In…arrow_forwardProgram - 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 9. Next, she calculates the number of calories that result from the carbohydrates, using the following formula: calories from carbs = carb grams x 4. Write a program that will make these calculations.

The letter identifies the column; the number identifies the row. See the image below. You will provide the functions that allow us to determine: if a chessboard square is either black or white, given its coordinates. If the row/column is valid or not for the standard chessboard For example, if we pass in “d” for the column and 4 for the row, your function that determines color should return the string: “BLACK”. If we pass in "k" for the column to your function that validates columns, that function should return the boolean False. Requirements: Your function for validating the column should be able to accept upper or lowercase strings as parameters. Your functions for validating the row should be able to accept integers or strings as parameters. Your function that determines black-or-white may assume that the input has been validated prior to us calling…arrow_forwardBad News Bearers Introduction There is some bad news to be delivered, and X has taken on the dangerous mission. Nobody really wants to be the one to take the news; the way goes through enemy territory and, even if the messenger gets through, the classic fate of the bearer of bad news may be waiting. (Let's just say, this is how the phrase "Don't shoot the messenger" became relevant.) To determine which messenger will be sent, X sits all of his messengers down in a circle, selects a number, and starts to count off. Messengers are allowed to leave the circle one by one, and the last messenger left is the one who will deliver the bad news. The counting off procedure is slightly unusual, however, because it is actually the messenger after the last one counted who gets to leave the circle. Consider the following example with 5 messengers, in which the number selected for counting off is 7. We'll start at the "head" of the list and move forward. Since it is circular, the "head"…arrow_forward

Suppose that the mean (average) of n numbers x1, x2, . . ., xn is x. Then the standard deviation of these numbers is:S=sqrt(((x1-x)^2+(x2-x)^2+...+(xi-x)^2+...+(xn-x)^2)/n)arrow_forwardLab Goal : This lab was designed to teach you more about recursion.

You will only take an element off of one end or put an element back on one end because you are being lazy. But you have friends in recursion who can assist you.Please provide the recursive code as well as a paragraph with the friend's description of the algorithm.2. Now imagine that you lack friends but have a stack. Quickly design an iterative programme to address this issue. Include loop invariants and other crucial stages that are necessary to describe an iterative method.3. Trace both of these scripts separately.
