Crate takuzu [−] [src]
A Takuzu (a.k.a. Binairo) solving library.
About
Takuzu is a number puzzle, sometimes called binary sudoku.
The objective is to fill a grid with 0s and 1s while
observing the following rules:
- no more than two of either number adjacent to each other in one direction.
- each row and each column must contain an equal number of
0s and1s. - no two rows and no two columns are the same.
The grids are squares of even size. A valid grid must have one and only one solution. The solver will find and return all the valid solutions though.
Format
The grid must be represented with the following characters:
0, 1, . for a missing number, and one \n at the end of each row.
(The final \n may be omitted though.)
