Sudoku Kata
The rules of the Sudoku are as follows :
You fill in all the squares in the grid so that each row, column and each of the 3x3 squares contains all the digits from 1 to 9 without repeats or omissions.
N.B : A well-posed board has a single solution in sudoku.
Given a partially completed board:
|
0 0 6 0 0 0 0 0 0 |
2 9 0 0 8 6 0 7 0 |
3 4 0 0 9 2 0 0 1 |
|---|---|---|
|
1 0 0 0 0 8 0 9 0 |
0 0 8 0 2 0 1 0 0 |
0 7 0 1 0 0 0 0 8 |
|
7 0 0 5 1 0 0 6 4 |
0 3 0 8 4 0 0 0 0 |
0 0 0 0 0 0 0 0 0 |
The solver should give a single result:
|
8 5 6 3 7 1 2 4 9 |
2 9 1 4 8 6 5 7 3 |
3 4 7 5 9 2 6 8 1 |
|---|---|---|
|
1 2 5 4 3 8 6 9 7 |
3 6 8 9 2 7 1 5 4 |
4 7 9 1 6 5 2 3 8 |
|
7 8 2 5 1 3 9 6 4 |
6 3 5 8 4 9 7 1 2 |
9 1 4 7 2 6 8 5 3 |
