You may have heard of a puzzle where you must fill in squares for a 9x9 grid with the digits one through nine using the following rules. The digits can appear only once in each row and column. Furthermore, the 9x9 grid is divided into nine regions of 3x3 grids, and the digits can only appear once in each region. Given the following puzzle, write a recursive solution using backtracking that solves such a puzzle. 6 9 9 3 8 462 1 6 8 3 3 7 2 4 6 8 15 2 1 7 3 93 7 543 943 9 1 6

I have seen some solutions to this problem in Bartleby's library that make no sense to me. I am learning C++, more specifically working with dynamic integers and have become confused with what has been provided previously by others. Using dynamic integers, can I get help with creating a class named 'largeIntegers' so that an object of this class can store an integer of any number of digits. If I could get help with setting up operations to add, subtract, multiply, and compare integers stored in two objects. Also, if someone could explain and help myself create constructors to properly initialize objects and functions to set, retrieve, and print the values of objects. There are three files I am working with: main.cpp, largeIntegers.h, and largeIntegers.cpp largeIntegers.cpp #include <iostream> using namespace std; largeIntegers.h //Specification file largeIntegers.h #ifndef H_largeIntegers #define H_largeIntegers #include <iostream> using namespace std;…

mplement a Java program that applies the Newton-Raphson's method xn+1 = xn – f(xn) / f '(xn) to search the roots for this polynomial function ax6 – bx5 + cx4 – dx3+ ex2 – fx + g = 0. Fill out a, b, c, d, e, f, and g using the first 7 digits of your ID, respectively. For example, if ID is 4759284, the polynomial function would be 4x6 – 7x5 + 5x4 – 9x3+ 2x2 – 8x + 4 = 0. The program terminates when the difference between the new solution and the previous one is smaller than 0.00001 within 2000 iterations. Otherwise, it shows Not Found as the final solution.
Overall Requirements: Use only Java features that have already been introduced in the course (e.g., loops, arrays, and functions but not objects). The functions must not mutate the argument array(s). You may assume that the array arguments to all functions are not null. All samples sent to standard audio must be between –1 and +1. Note that it is possible that the input samples to each method may not be between –1 and +1. The functions should operate as specified. While you should not play samples whose absolute value is greater than 1, it’s fine to manipulate such values along the way. However, to ensure that your final sample compiles with this requirement, you may want to implement one of the private helper methods: clamp() and normalize(), and then process your final sample before sending it to standard audio. You must not add public methods to the API; however, you may add private methods (which are accessible only in the class in which they are declared). Assignment: Audio…

Note: Please answer the question in C++ only: Citizens of Byteland play the game regularly. They have blocks, each of which represents some integer from 0 to 9. These are arranged together in a random fashion without having to remember that the first block is never 0. Once they form a number, they are read in reverse order. check that the number and its reverse are the same. If both are the same, the player wins. Such numbers are called palindromes. Ash happens to see this game and wants to simulate it on the computer. As a first step, it wants to take input from the user and check if the number is a palindrome and declare whether the user wins or not. Input 1 331 Output loses
Solve in JavaBuying/Selling Shares of Stocks Buying and selling shares of stocks of listed companies is a typical task to do among investors. Of course, this would result in a capital gain (or loss) when the shares are sold. This is computed as the difference between the shares' selling price and the price was originally paid to buy it. When an investor has a single share of stock, the process is easy. However, when (s)he sells multiple shares of stocks, bought over a period of time and possibly with different prices, the first step is to identify which shares of stocks are to be sold. There are two accounting principles (protocols) that are followed depends on the market of stocks: the shares bought last to be sold first, and the other is to sell the shares that stayed the longest. You are required to implement a program to calculate the possible capital gain/loss using these two protocols. This would facilitate the process for investors to know which market to go for and invest their…
