1. Use one-dimension array to record a sudoku puzzle / solution data. (Previous version were using
301+
two-dimension array).
302+
303+
Once you still want to get a two-dimension array, here is an example shows that.
304+
305+
```typescript
306+
import { toMatrixStyleBoardData } from '@algorithm.ts/sudoku'
307+
308+
// Convert the two-dimensional array to one-dimensional array.
309+
const puzzle = oldStylePuzzle.flat()
310+
311+
solver.solve(puzzle, solution)
312+
313+
// Convert the one-dimensional array to two-dimensional array.
314+
const oldStyleSolution = toMatrixStyleBoardData(solution)
315+
```
316+
317+
2. `createSudokuBoard()` is renamed to `createSudokuBoardData()`.
318+
3. `fillSudokuBoard()` is renamed to `fillSudokuBoardData()`.
319+
4. `copySudokuBoard()` is renamed to `copySudokuBoardData()`.
320+
5. `checkSudokuSolution` is renamed to `checkSudokuSolution`.
