sudoku 3x3

10.1 After the national day, well-known bloggers: LAVIEWPBT http://www.cnblogs.com/Imageshop/Launched a small activity that optimizes the ambiguity of the middle value of a 3x3.I also participate in, today Bo Master LAVIEWPBT shared a good clahe code. Free spirit, really for its praise.So I also share this fastest 3x3 median fuzzy code.Written by: LAVIEWPBT, written in: 2015.10.16, contact qq:33184777///Ref
