QUESTION
I am trying to create a dynamic table of a sudoku app I am working on but I am unable to see why this code wouldnt work. my base app passes in a ref hook and sends the 9x9 array to the Grid component

QUESTION
I made a sudoku solving code in python, closely following the solution given on GeeksForGeeks, but my code runs really slowly, albeit producing correct results.
It took over 2 minutes to run, whereas the GeeksForGeeks code took under a second to solve 2 such Sudokus:

Answered 2022-Mar-20 at 20:04If you want to know why your code is slow, run it under a profiler. For example cProfile that comes with Python.
I have saved your code as mydoku.py, and ran the following command:

I have solved the sudoku using JavaScript but I want to print -1 if the given sudoku has no solution. I have done it using recursion and have exhausted all the ways that I could think of. Please help me solve this question for unsolvable sudoko's.

QUESTION
I am creating a sudoku gameboard and I need to draw some lines to divide the 3x3 boxes. The board is made out of buttons, so what I am trying to do is change the border color from the buttons on the 3rd and 6th column, & line.
The problem I am facing is that I can't add on a button 2 borders: right and bottom. The Js code only adds one attribute at a time, using elem.setAttribute. So I tried a function that supposedly lets you add more than 1 attribute, but it doesn't seem to work.
Where is the bug?

Answered 2022-Jan-19 at 16:54If you only use setAttribute for styling, you could fix it like this:
QUESTION
Sudoku is a well known CSP and, in this case, LC problem. I don't need the solution, which follows.
My question is why does self.DOMAIN = "123456789" (line #4) work, whereas self.DOMAIN = map(str, range(1, 10)) (line #5) does not? Are they not equivalent?
ANSWER
Answered 2022-Jan-15 at 19:46You are suffering confusion between "generator" and "container".
Consult type( ... ) to tell the difference between them.
Python generators are "lazy", for excellent technical reasons. Sometimes we can get away with just evaluating the first K items of an infinite generator.
In your method you want everything greedily pulled out,
and then stored in a container.
The conventional way to phrase this is to wrap map with list:
QUESTION
I was wondering how to solve this Sudoku board in Python using Human input and Computer solving. I have a Human and Computer solve def. I tried using rows and columns to solve and it just wouldn't print the results on the board every time it would work. I tried doing these using things such as for 'i in range'. But when I would run the program it would be working but not printing the results each time it was solving it. Thank you!
...ANSWER
Answered 2022-Jan-09 at 15:13You would solve it programmatically the same way you would solve it as an intelligent human.
Have a set of discovery rules that you apply to groups (rows, columns, or 3-by-3s) to eliminate possibilities, or select values where there is but one possibility.
For example, consider the first three rows in the first puzzle:
QUESTION
I'm writing a python program making use of ortools to solve a problem. I'm trying to change for loops as much as possible using list comprehension. Almost all gone well, but there is one I can't get changed
The original one works well:
...ANSWER
Answered 2022-Jan-08 at 17:48As stated by Craig there is currently no chance to reproduce your program so I have to make some assumptions. I am assuming that the s.Add() in your first code sample actually uses one \t more than shown in your snippet. I would argue that at least the parantheses within the list comprehension are not set properly.
So my comprehensed list is referring to an original code looking like:

I have the following problem. My task is to create a double bond between my sudoku field object and its graphical form in the GUI. So far I've managed to come up with something like this.

QUESTION
I am learning recursion and came through this code (not mine: https://github.com/kying18/sudoku) and cannot figure out why the variable example_board changes value. It is never addressed again and no other variable is linked to it? I tested it and it does!
Here is the condensed version of the relevant code:
...ANSWER
Answered 2022-Jan-03 at 18:56When printing in the line: "print(solve_sudoku(example_board))" example_board is passed into solve_sodoku. The solve_sodoku function then changes it values in this line: "puzzle[row][col] = guess" as puzzle is referencing the example_board variable and one of its value is being changed to guess.
Hope this helped!
