This question is also a very violent search ......
Because the uniqueness is empty at the beginning, and there are only a lot of size restrictions, there is no need to worry about where to start the search, and then determine whether it is legal after the brute force search.
The most disgusting question is reading. Now I learned a trick to determine which part of the grid is located and use Lim [g] [I] [J] to indicate the relationship between the two grids I and j in the G Palace, the pro

This article examples for everyone to share JS Lucky Draw nine Sudoku large turntable effect, for everyone's reference, the specific content as follows
Implementation code:
The above is the entire content of this article, I hope to learn JavaScript program to help you.
In this paper, we introduce the corresponding method of JavaScript to realize nine Sudoku, and share them for everyone's reference, the specific contents are as follows
Realize the idea:1, each lattice input value must be a number;
2, the input value can not be repeated;
3, the input value can not be less than 1 or greater than 9;
4, the value can not be empty;
5, add a total of 8, respectively, three horizontal, vertical three, two diagonal two

The overall code of the blog's thinking is very clear, it is worth learning.The above blog code DFS knowledge output an array of answers, if the number is unique to multiple solutions, simply change the DFS code simple (as follows):
void dfs (int row,int col) {if (row>9)//if row exceeds 9 lines, direct output {for (int i=1; i
The Overall code is as follows:
#include
The above code looks pretty long,

The effect of the selection is actually the alternating results of two pictures, because only for the 240x320 this style, so it may be written in many places, the following to some o

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
