如，玩家需要根据9×9盘面上的已知数字，推理出所有剩余空格的数字，并满足每一行、每一列、
每一个同色九宫内的数字均含1-9，不重复。

数独的答案都是唯一的，所以，多个解也称为无解。
本图的数字据说是芬兰数学家花了3个月的时间设计出来的较难的题目。但对会使用计算机编程的你来说，恐
怕易如反掌了。

本题的要求就是输入数独题目，程序输出数独的唯一解。我们保证所有已知数据的格式都是合法的，并且题目
有唯一的解。

格式要求，输入9行，每行9个数字，0代表未知，其它数字为已知。
输出9行，每行9个数字表示数独的解。(For example, the player needs to deduce the number of all the remaining spaces based on the known numbers on the 9 * 9 disk, and satisfy each row, column, and column,
The number in each of the nine colors is 1-9, not repeated.
The answer to Sudoku is unique, so multiple solutions are also known as no solutions.
The figures in the figure are said to be difficult subjects devised by Finland mathematicians for 3 months. But for you who can use computer programming, fear
If the breeze.
The question here is to enter Sudoku puzzles, and the only solution for sudoku. We guarantee that all known data formats are legal and subject
There is only one solution.
Format requirements, enter 9 lines, 9 digits per line, 0 represent unknown, and other numbers are known.
Output 9 lines, each line of 9 numbers indicate Sudoku solution.)
