It started as an exercise in Java. Afterwards, I wanted to recreate it in C#, but more ideas kept coming up and this is the result. My teacher told me about the next topic being multi-dimensional arrays and that we would take a look at Sudoku. So, I was thinking about a generator, which was relatively easy except for the backtracking part of the algorithm because that was something new for me. After I wrote the program, I wanted to recreate it in C#, which led to this project.

After recreating it, I wanted to make an usable app out of it:

1. Generate A Valid Sudoku
2. Allow For Input For The Sudoku To Solve
3. Check Whether The Input Is A Valid Board
4. Solve The Sudoku
5. Allow For Export To A TXT File

• You Start In A Menu Where You Can Press (G) To Generate A Sudoku Or (S) To Solve One.
• When You Decide For (S)olving One You Can Enter Each Row With Or Without WhiteSpaces Depending On What You Prefer.
• If You Enter An Empty Line It Will Reset To Row [1]
• If You Have Anything Other Than Numbers In Your Input The Row Will Reset To [current] So You Don't Have To Start From The Beginning.

I Do Not Check For Permissions So Make Sure The App Can Create The File If It Does Not Exist Or Open And Append To An Existing One.
