SudokuMP
SudokuMP solves sudoku puzzles given a txt file arranging the puzzle and the size of the puzzle. There are two methods to solve said puzzles the brute force method and the humanistic solver. Profiling wasn't performed on the humanistic solver since it manages to solve all the 16x16 puzzles extremely quickly the worst of them still being under 12ms. The project can be found here: SudokuMP
The following is a example of the program running with an example input and the output afterwards.
16x16 easy 1
