# Sudoku_Func

A functional program (in haskell) to solve sudokus.

## Usage

Under the same directory as the `sudoku.hs` file:

```haskell

import Sudoku

```

Inside the module are:

```haskell

type Matrix a = [[a]]

type Cell = Maybe Int

newtype Sudoku = Sudoku (Matrix Cell)

type Block = [Cell]

type Wave = [Int]

type Pos = (Int, Int)

type Info = (Cell, Wave)

isSudoku :: Sudoku -> Bool

isFull :: Sudoku -> Bool

fromString :: String -> Sudoku

getRows :: Sudoku -> [Block]

getColumns :: Sudoku -> [Block]

getBoxes :: Sudoku -> [Block]

getWaves :: Sudoku -> Matrix Wave

binded :: Sudoku -> [(Pos, Info)]

getBlanks :: Sudoku -> [(Pos, Info)]

conflict :: Sudoku -> Bool

replace :: Sudoku -> Pos -> Cell -> Sudoku

solve :: Sudoku -> [Sudoku]

```
