Sudoku Validation

Write a sudoku validator. This function should return true if the 2-D array represents a valid sudoku and false otherwise. To be a valid sudoku:

1. Each row must have the digits from 1 to 9 exactly once.
2. Each column must have the digits from 1 to 9 exactly once.
3. Each 3x3 box must have the digits from 1 to 9 exactly once.

Examples

sudokuValidator([
  [ 1, 5, 2, 4, 8, 9, 3, 7, 6 ],
  [ 7, 3, 9, 2, 5, 6, 8, 4, 1 ],
  [ 4, 6, 8, 3, 7, 1, 2, 9, 5 ],
  [ 3, 8, 7, 1, 2, 4, 6, 5, 9 ],
  [ 5, 9, 1, 7, 6, 3, 4, 2, 8 ],
  [ 2, 4, 6, 8, 9, 5, 7, 1, 3 ],
  [ 9, 1, 4, 6, 3, 7, 5, 8, 2 ],
  [ 6, 2, 5, 9, 4, 8, 1, 3, 7 ],
  [ 8, 7, 3, 5, 1, 2, 9, 6, 4 ]
]) ➞ true
