Hard Twodoku Puzzles
A Double Sudoku puzzle is a variation of the traditional Sudoku puzzle that consists of two overlapping Sudoku grids. In this variation, the two grids share a middle square, which is a 3x3 square that belongs to both grids. The challenge is to solve both Sudoku puzzles simultaneously, ensuring that the numbers placed in the overlapping region satisfy the constraints of both grids.

The rules of Double Sudoku are similar to those of regular Sudoku:
- Each row must contain the numbers 1 through 9 with no repeats.
- Each column must contain the numbers 1 through 9 with no repeats.
- Each 3x3 subgrid, in both grids, must contain the numbers 1 through 9 with no repeats.
- Additionally, in the overlapping region, the numbers must satisfy both sets of constraints.
