Declaring and Defining the function

A set of statements, which performs a particular task is called a function. The program gains modularity by using function. The application is quite easy to understand, read, and edit when they are created with functions. The developer/programmer creates a function and uses main() to call the function. Once the function gets executed, the control is transferred to the main program.

Question

please write Java code for the following solution

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.

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…

can i just get the code
i cant use static void Main(string[] args) for this assignment for C# this is what I have to work with using System; using static System.Console; class GuessingGame { static void Main() { // Write your main here } } This problem relies on the generation of a random number. You can create a random number that is at least min but less than max using the following statements: Random ranNumberGenerator = new Random();int randomNumber;randomNumber = ranNumberGenerator.Next(min, max); Write a program named GuessingGame that generates a random number between 1 and 10. (In other words, in the example above, min is 1 and max is 11.) Ask a user to guess the random number, then display the random number and a message indicating whether the user’s guess was too high, too low, or correct.
How can I express the following situation in Java programming? Orcs, Hobbits, and Tom Bombadil We have n-1 Orcs and n Hobbits who want to cross a river. We also have Tom Bombadil who wants to cross as well. Only Hobbits and Tom Bombadil can row the boat (don’t ask　me why!) At all times, the number of Hobbits on either side of the river must be greater or equal the number of Orcs on that side (unless there are no Hobbits on that side), or the Hobbits will be killed by the Orcs! If the boat holds 2, with n=4 or more, the problem has no solution. If the boat can hold 3, then up to n=5 can be solved. If the boat can hold 4, any number (n) Hobbits can cross. So -- if n = 1,2 or 3 - use a boat of size 2. If n = 4 or 5 - use a boat of size 3. If n > 5 use a boat of size 4. If n <0 invalid input if n = 0 no output.
