Sudoku is a test of eyesight and logic of the small game, the key in the "single" word, can not be repeated, the block can not be repeated. Today I will introduce a "loop + recursion + backtracking" method to use Java program for us to complete Sudoku.The code is then explained:1 ImportJava.util.HashMap; 2 ImportJava.util.Map; 3 4 public classT2 {5 public static final int n=3; 6 public static voidMain (string[] args) {7 int x[][]={8 {0,2,0,0,0,9,0,1,0

You must have heard of the Sudoku game. As shown in the figure, the player needs to infer all the remaining space figures according to the known numbers on the 9x9 disk, and satisfy each row, each column, each nine within the same color 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 difficult subj

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

Recently, Singapore Prime Minister Lee Hsien Loong also wrote a code published, a general look, unexpectedly, is the code of coefficient alone! Just a few days ago, the main algorithm of Sudoku is to use backtracking. Backtracking method at that time when beginners in the thinking of the comparison twist, not easy to write right. After writing a few backtracking algorithms, I finally got a little bottom in my heart. The backtracking code is typically

You should keep the original relative order of the two parts of the linked table node. Examples The given list 1->4->3->2->5->2->null, and x=3 returns 1->2->2->4->3->5->null train of ThoughtSimple idea: is to create a new two list of linked lists to store less than X and greater than X, and then merge the two list.
