sudoku 9x9

Recently nothing to do, according to video Tutorial wrote a Sudoku game, very rough there are many places to modify. Let's talk about this game.1. Customize a View control to display a 9*9 grid on the screen, which is actually a horizontal drawing of 8 lines, a vertical drawing of 8 jumpers, and then a few of the lines to be bold. So that's the 9*9 lattice.2. Initialize the numbers on the game interface with a string1 String str_int = "360000000004230

A few days ago, I saw an interview book with a question about the generation of the sudoku game. So I wanted to implement it myself, read the code of others, and modified some of it myself, the core idea of the code is to use deep priority search. When the searched node meets the condition, search for the next point. Otherwise, the code will be rolled back. Program running diagram: Public void getSudoku (int [] [] array, LEVEL level) {clear (array);

Write a program to solve a Sudoku puzzle by filling the empty cells. Empty cells are indicated by the character‘.‘. You may assume that there will be only one unique solution. A Sudoku puzzle... ... And its solution numbers marked in red. The input of a question is valid. With the backtracking method, we only need to check whether the newly added values are valid in rows, columns, and small squares, and

Write a program to solve a Sudoku puzzle by filling the empty cells.Empty cells are indicated by the character '. You could assume that there would be only one unique solution. The following algorithm uses the idea of breadth search, in each empty cell, finds all available numbers, fills in an available number, and puts the current Sudoku status into the queue. The code is as follows: Class Solution {Publi

After a few days of work free time to write a Sudoku game on Android, today also applied for several release platform account, released, Google Play to receive 25 knives, and this in the mainland basic access is not, so temporarily did not buy. Writing applications on the mobile platform is fun and feels like a simple application, but it's hard to write interesting apps with elegant code. I've got a new idea lately, and I've always wanted a phone app

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.

The implementation of this algorithm is to simulate the thinking and computing process of the human brain. If you need it, you can refer to it. 1) when we get a question, we will first follow the conditions we already know, sort and analyze the data. It is equivalent to writing all "OK items" in the 9th Palace, and marking "Possible options ". Function refreshStat () 2) afterwards, the thinking will enter the cycle of speculation/verification. In cells 9, you can try "Possible options" to verif

Test instructionsGive you a 9*9 matrix that separates the two elements adjacent to the same row with a single space. Where 1-9 represents the already filled number of the position, the question mark (?) indicates the number you want to fill. The solution of this Sudoku is output and there is only one solution for each group.Ideas:Record the vacant place, each vacant place has 9 in the state, DFS + pruning processing other, with scanf input, get () tle
