The past few days to try to write graphics program with the Java swing, while learning to write a simple Sudoku game, in the process of writing learned a lot about swing things, but also for the programming of the graphical program has a little bit of a simple understanding: Good its prior to the device, since the writing graphics program first to play an IDE skilled, do not care what the IDE, like wh

Use the DLX algorithm to perform a Sudoku game.Java beginners, algorithm code is converted from C code.DLX. Java is an algorithm class, and Sudoku. Java is an interface class.It takes less than 10 ms to describe the world's most difficult

Problem:Determine if a Sudoku is valid, according To:sudoku puzzles-the Rules.The Sudoku board could be partially filled, where empty cells is filled with the character ‘.‘ .A partially filled sudoku which is valid.Note:A Valid Sudoku board (partially filled) is not necessarily solvable. Only the filled cells need to b

Sudoku is a test of eyesight and logic of the small game, the key in the "single" word, can not be repeated, the block can not be repeated. Today I will introduce a "loop + recursion + backtracking" method to use Java program for us to complete Sudoku.The code is then explained:1 ImportJava.util.HashMap; 2 ImportJava.util.Map; 3 4 public classT2 {5 public static

Detailed designgame data structure designObviously, the only place where you need to store data is the nine map section.For maps, it is obvious that we can use two-dimensional array int [] [] game; To store the data in the map. However, although the two-dimensional array of int is straightforward, there are some inconveniences, such as the rich built-in processing method without the set. So, obviously, in the game map generation process, some auxiliary data we can adopt the

Title Description:Write a program to solve a Sudoku puzzle by filling the empty cells.Empty cells is indicated by the character ‘.‘ .Assume that there would be is only one unique solution.A Sudoku Puzzle ...... and its solution numbers marked in red.Problem Solving Ideas:The subject uses backtracking and HashSet methods. For each blank position, the temptation is to use a number between ' 1 '-' 9 ', if the

This article shares the code of the small program for solving the problem of Sudoku. I used Java to write a small program for solving the problem of 9x9 sudoku. I used the exhaustive method to solve the problem. The code is as follows: Package Test; public class SensibleGam

Python implements the code for solving the sudoku program. I accidentally found that a Sudoku game came along with the linux system and played a few games. Instead, I was a Sudoku cainiao. I had never played it before, and I had to make a mess in a few steps. Therefore, it is fun to use the powerful computing power of

Seek Sudoku, only ask to make an answer.Just beginning to understand test instructions wrong, think the answer is unique, so did not do it for a long time, found that the answer is not unique after using backtracking.

A few days ago LP play Sudoku, play to master a variety of abused, I looked to say, minutes to help you do it out,The result is of course not done.So the internet search the next Sudoku code, read the next C code, mostly recursion and the like (such as http://blog.sina.com.cn/s/blog_9e16dc4d01013s1y.html)So think, can
