In this paper, we describe the method of Python's implementation of Sudoku algorithm. Share to everyone for your reference. Specific as follows: #-*-Coding:utf-8-*-"Created on 2012-10-5@author:administrator" from collections import Defaultdictimport Itertool SA = [[0, 7, 0, 0, 0, 0, 0, 0, 0], #0 [5, 0, 3, 0, 0, 6, 0, 0, 0], #1 [0, 6, 2, 0, 8, 0, 7, 0, 0], #2 # [0, 0, 0 , 3, 0, 2, 0, 5, 0], #3 [0, 0, 4, 0, 1, 0, 3, 0, 0], #4 [0, 2, 0, 9, 0, 5, 0, 0,

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 {, 0 },19 {5, 0, 0, 0, 0, 0, 0 },20 {, 0 },21

Today the idea is determined, roughly for the following structure:1. Define the data in the game and initialize the lattice data.2. Define touch events.In the view class, overwrite the Ontouchevent (Motionevent event) method.3, inherit the dialog class, customize a dialog.4, do the above preparation, we can re-view class, the game layout, and to operate.5. Call the MyView object in the main class.Estimated time: 5 days, each day to complete the encoding of a class.Today's content:The class of th

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
