Chapter 7, Problem 7.25E
(Eight Queens: Brute Force Approaches) In this exercise, you'll develop several brute-force approaches to solving the Eight Queens problem introduced in Exercise 7.24.
a) Solve the Eight Queens exercise, using the random brute force technique developed in Exercise 7.23.
b) Use an exhaustive technique, i.e., try all possible combinations of eight queens.
c) Why do you suppose the exhaustive brute force approach may not be appropriate for solving the Knight's Tour problem?
d) Compare and contrast the random and exhaustive brute force approaches in general.

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:

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.…
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

- Complete the following Java method. This method takes in an array of Strings. The method's task is to find out how many times the most common character frequency appears in all of the array's Strings. As an example, for the array ["mouse", "cat", "dog"], the method should return 9, since the characters "m", "u", "s", "e", "c", "a", "t", "d", and "g" appear only once and this frequency (1) appears 9 times. The character "o", appears twice. This frequency (2) appears only once. Therefore, 9 must be returned. Also, if a character appears multiple times in one String, you must count every occurrence. For example, in the word "houses", the character "s" appears twice. Therefore, each occurrence of "s" must be counted. If there is a tie at the completion of the method, you must still return how many times the most frequent character frequency occurred. Furthermore, in your implementation, you must make use of the Java Class Library's HashMap class in order to map particular characters to…arrow_forwardArtificial Intelligence (Part - 1) ==================== The Towers of Hanoi is a famous problem for studying recursion in computer science and searching in artificial intelligence. We start with N discs of varying sizes on a peg (stacked in order according to size), and two empty pegs. We are allowed to move a disc from one peg to another, but we are never allowed to move a larger disc on top of a smaller disc. The goal is to move all the discs to the rightmost peg (see figure). To solve the problem by using search methods, we need first formulate the problem. Supposing there are K pegs and N disk.

Recursion write a Java program.A perfect number is a number whose factors, excluding the number itself, also add up to that number.For example 6 is a perfect number since its factors (other than 6 itself) 1, 2, and 3 also add up to 6 (i.e.,1+2+3 = 6).

- Task 4: The first problem that you solve recursively is to implement enoughGate() to check if the dogMaze has at least two gates (one for the entrance and one for the exit). This problem must be solved recursively, however there is no limitation on what type of recursion (i.e., direct or indirect recursion) you use . As a reminder, a direct recursion refers to the function that calls itself to solve the given problem. However, by indirect recursion, more than one function involves in solving the problem. It is possible that a non-recursive function solves a small part of the problem and then calls the recursive function to finish the job. /** * This method returns true if the number of * gates in dogMaze >= 2. * @return it returns true, if enough gate exists (at least 2), otherwise false. */ publicboolean enoughGate (){ // insert your code here.

Your objective is to receive the tuple a1, a2,..., a and return the tuple an, an1,..., a1 that has been inverted. 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. On a computer, step by step compare and contrast their calculations.arrow_forward

Recursion Find how many possible combinations that a number can be decomposed into the multiple of integers (smaller than the number itself) by a recursion function.Suppose we have a positive number Y as input, and it need to be decomposed into the multiple of several integers, Yi, where each Yi, is smaller than Y(e.g., Y=Y1∗Y2∗ Y3∗...∗Yn).

Your version of the game will imagine only a SINGLE suit of cards, so 13 unique cards, {2,3,4,5,6,7,8,9,10,J,Q,K,A}. Upon starting, you will be given two cards from the set, non-repeating. Your program MUST then tell you the odds of receiving a beneficial card (that would put your value at 21 or less), and the odds of receiving a detrimental card (that would put your value over 21). Recall that the J, Q, and K cards are worth ‘10’ points, the A card can be worth either ‘1’ or ‘11’ points, and the other cards are worth their numerical values. FOR YOUR ASSIGNMENT: Provide two screenshots, one in which the game suggests it’s a good idea to get an extra card and the result, and one in which the game suggests it’s a bad idea to get an extra card, and the result of taking that extra card.arrow_forward
