Let's make a sudoku solver in 5 minutes (Backtracking) - Inside code 

Discover the new graph theory algorithms course: inscod.com/graphalgo 🔴 / \ 🔵-🔴 | | 🔴-🔵

The video was easy to follow and the bit at the end was nice to see the function working step by step to show the concept of backtracking. You definitely worked super hard on this video. well done

FINALLY I SOLVED THIS SHI

it didn't work for me

It was the best video that I watched about sudoku solution and backtracking! It was very clear and simple to understand. Thank you !

My dear you tuber , First solve sudoku in paper and tell about algorithm for program THE ALGORITHM WILL NOT WORK #error

Great minimal coding using recursion. And animation is real added bonus. The video itself is a good example in its own class to emulate by other educators perhaps.

الله يبارك the animation is really cool and the code is neat keep it up man you are doing wonders

Very cool animation, very elegant solution! Thank you so much.

I found myself spending days on this - it feels so disappointing! Is this normal?? I got to try solve it(did not finish) in a longer approach too, probably inefficient - i feel defeated! I did not use backtracking. I seem to get confused with recursion every time despite having lots of experience! Is this normal? Is it possible to come up with this solution from the get go in 5 minutes if one has never done it before? Thank you for sharing this video - it's been very well explained - + 1 like and subscribe.

I enjoied very much watching the video. I think that some other solution type, may try breath first strategy, and also, simply to complex coroborating techniques to produce the next breath first aproximation of all pissiblities for any cell to be filled with digits, that is also meant to find, in the end, the unique solution, if the algo work properly. :-)

WOW. I always expected making a Sudoku solver to be insanely complicated, but clearly not. I actually suck at solving Sudokus, but I'm planning on making a Sudoku solver for a school project, and this is perfect. I didn't expect to understand anything at all when I clicked on this video. I'm really surprised how easy this seems. I hope it is how it seems 🤞

He solves every coding problem flawlessly and he's so easy to follow.

This was amazing! I actually understood the sudoku backtracking algorithm finally.

i make it with C

brilliant explanation => thank you so much Bro😘 please continue

I get how the conditions n i get how it checks every number to see if its valid but i still dont get how it goes back can anyone help me out

the best of the best for sudoku solution. THANK YOU SO MUCH😍

I love you! no homo. Best explanation I have ever seen. It allowed me to organize my thoughts. Other instructors make it more complicated than what it is.

thank you for this video, great timing

This seems like it would take forever to run

Great quality.

how do i make my output show all its trials and errors like at 5:05

I always wondered if we can succesfully test some rating 1400 chess program based on limited hardware processing power and some software idea that I would formulate it as progressive complexity breath first alpha beta prunning also stable kinda search/ stable first minimax search, breifly. Thank You! :-)

How to know if the grid has more than one solution?

If the solver stops when the row is = 9 then how will you do the last row?

your source code in github is follow 'backtraking' algorithm?

How do you edit your videos?

Thank you.

Python or Java?

But if we return only true how to get the result? How to grab the puzzle?

amazing explanation and animation! thanks man
