# sudoku_ruby
Sudoku class in Ruby
## sudoku.rb
### example:
Create sudoku ( arr[N][N] , default: size = 3 )
```
small_sudoku = [
[4,3,2,1],
[2,1,4,3],
[1,2,3,4],
[3,4,1,2]
]
normal_sudoku = [
[nil, 9, 5, 7, 4, 3, 8, 6, 1],
[4, 3, 1, 8, 6, 5, 9, 2, 7],
[8, 7, 6, 1, 9, 2, 5, 4, 3],
[3, 8, 7, 4, 5, 9, 2, 1, 6],
[6, 1, 2, 3, 8, 7, 4, 9, 5],
[5, 4, 9, 2, 1, 6, 7, 3, 8],
[7, 6, 3, 5, 2, 4, 1, 8, 9],
[9, 2, 8, 6, 7, 1, 3, 5, 4],
[1, 5, 4, 9, 3, 8, 6, 7, 2]
]
sudoku_1 = Sudoku.new(normal_sudoku)
sudoku_2 = Sudoku.new(small_sudoku, 2)
```
Print board:
```
sudoku_1.prints
```
output:
```
| 9 5 | 7 4 3 | 8 6 1 |
| 4 3 1 | 8 6 5 | 9 2 7 |
| 8 7 6 | 1 9 2 | 5 4 3 |

Set value in board:
```
sudoku_1.set(0,0,2)
```
Check correct solve:
```
sudoku_1.solve?
```
output:
```
puts sudoku_1.solve? #=> false/true
```
