说明：  自己以前写的数独解算程序，解算速度快，只能解算单解的数独问题，使用控制台界面，虽然不是GUI的，但是设计界面就花我几天时间。算法是自己设计的，没有参考太多网络资料，可以供需要研究数独算法的朋友参考。
(I used to write their own Sudoku solver, It works speedly, while only single solution Sudoku problem will be done. with the console interface, although not GUI, but the design interface, I spent a few days. Algorithm is own design, there is no reference to many network information,it can be a refer to those who need arithmetic about SUDUKU.)
