I want a function that can solve a Sudoku puzzle. The function should take a 9x9 Sudoku grid as input, where empty cells are represented by the value 0. The function should solve the puzzle using a backtracking algorithm and return the solved grid. function should solve the puzzle using a backtracking algorithm and return the solved grid. If the puzzle is unsolvable, it should return None. function should also validate the input grid to ensure it is a valid Sudoku puzzle.

I would like to have a function that solves sudoku puzzles. The input to this function should be a 9x9 Sudoku grid, and blank squares should be represented by 0. The function should use a backtracking algorithm to solve the puzzle and return the solved grid. If the puzzle is unsolvable, then None should be returned, and the function should verify the validity of the input grid to ensure that it is a solvable Sudoku puzzle.
