The computer automatically generates the puzzles of the sudoku game It is really not easy to come up with all combinations that meet the conditions (mainly many, printing is very slow ). But our goal is to get a new combination each time, and then randomly hide some numbers from the grid. Therefore, you only need to make a slight modification on the basis of solving the sudoku game algorithm. Therefore, the

Topic: You must have heard of the Sudoku game.such as "Figure 1.png", the player needs to be based on the known number on the 9x9 disk, to infer all the remaining space figures, and meet each row, each column, each of the same color nine within the number contains 1-9, do not repeat.The answer to Sudoku is unique, so many solutions are also called no solutions.The figures in this figure are said to be the d

Although DLX can improve efficiency .... But for NPC, there is no need to be too efficient, and there is only one point of test.So as long as Dfs fills in, until the spaces are all filled up, be aware of the update and recovery of global variables in DFS.As for the method of storage, just consider the non-repetition of each small block of each row in each column.#include #includeusing namespacestd;intCNT =0;//indicates the number of remaining spaces to fillstructpoint{intx, y;}; Point epts[Bayi+

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.

I. Introduction of the topicIn the large nine lattice of 9x9, there are 9 small nine gongge of 3x3 lattice, and provide a certain number of numbers. Based on these numbers, use logic and reasoning to fill the other blanks with numbers from 1 to 9. Each number can only appear once per Gongne, and each number can appear only once per row or column. This kind of game only needs the logical thinking ability, has nothing to do with the numerical operation. Although the play is simple, but the digital
