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

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…

How to create a program in java that calculates two derivatives while using arrays?  The program should prompt the user for the coefficients of a polynomial and its powers

Instead of using: print(f"You should be spending {hours_inhome} hours on homework outside of class every week") for a beginner in python what is an alternative to using "f" and the { } signs for when you type in print. Also can you explain what the f means and what "{ }" these signs are?

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.
