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 Java collection.Map G

Judging whether Sudoku is legal Please determine if a Sudoku is valid. The Sudoku may only be populated with partial numbers, where missing numbers are used. Said. Precautions A valid Sudoku (partial padding only) is not necessarily solvable. We just need to make the padding space valid. Sample Example algorithm publ

I usually like to play the sudoku game. I suddenly wanted to use a program to automatically solve the problem yesterday. The idea is to trace back and keep testing. The program code is as follows: 1 # include 23 /*4 {, 1 },5 {, 6 },6 {9, 0, 0 },7 {1, 2, 5, 0, 6, 0, 3, 4, 7 },8 {, 6, 0, 0, 9, 8, 5 },9 {, 9, 0, 2 },10 {, 0, 0, 4 },11 {, 9 },12 {6, 4, 0 }};13 */1415 int data [9] [9] = {16 {, 0 },17 {, 7 },18 {

Continue. Today we are talking about reading and writing record files. Because the sudoku implemented on the Brew platform is a binary file, it is used directly on Android. We plan to implement two functions: loadtilist (), load the question library, first load the question library file in the resource, and then load it from the resource as a datainputstream. There are few lines of code, as shown below: public static Boolean loadtilist (mainactivity

Sudoku is a time-consuming and brain-consuming game. Generally, it takes about one hour for a difficult Sudoku to play. I am a pseudo-Sudoku enthusiast and it takes several hours to reach a difficult Sudoku, as a result, I was too lazy to write a program to crack the attack. I hope someone will like it. Ideas: 1.

Dance chain algorithm and Sudoku solution Dance Chain Algorithm The dance chain algorithm is used to solve the exact coverage problem.The exact coverage problem can be understood as follows:Given a 01 matrix, look for a collection of rows, so that the columns in the collection exactly match each column with a 1. Example: Matrix⎛⎝⎜⎜⎜⎜⎜⎜01010001010011010101⎞⎠⎟⎟⎟⎟⎟⎟\begin{equation} \left (\BEGIN{ARRAY}{CCCC}
