Problem
How many possible unique ways are there to generate a Sudoku Puzzle?? I can think of only two possible ways 1) Take a solved Sudoku puzzle and shuffle the rows and columns 2) Generate a random number and check if it violates any Sudoku constraints, repeat untill number does not violate any Sudoku constraint for every square(theoretically possible but normally it leads to deadlocking ) Are there any other ways?
