Yes,it is and I am doing just that,but I don't know,why it is not working out. how do we check if input is an integer?
I am using the isdgiit() functiom.

Hi,I need help with the last test case,where the input is 5,my code is returning 5 as the output,but there is some confusion about the type of the output,whether it should be a string or an integer?

So you are saying that I have to check the board in three ways? Horizontally,vertically and by 3*3 rule? If yes then which rule has the final say in determining the completeness of the board?

can you please explain,how?

I am using python

After spending an entire day solving this kata,I have come to the conclusion that there is a bug in it:(. If my logic were faulty it wouldn't have worked for any of the sample tests but it is unbelievable that my code runs fine for 5 out of 6 tests and the one test it's not passing is giving all signs of a 'Finished' Board. so my code is showing it to be Finished.
I still ask for help,if I am doing something wrong,please correct me,I am solving the sudoku by 3*3 rule.

It is amazing how a seemingly easy problem takes so much time to solve(Or maybe I am not that good a programmer). Although it appears to be a simple condtional problem but it does require to be analaysed properly!

me too,feel so stupid after seeing my tens of lines written in a single line

Hey I am woking on this "Find the unique number" problem and I have passed 15 out of 16 tests. but there is this one test where the expected output is 0 and my code is returnig 1. Since my code is working fine for all ohter conditions and the test case is not visible to me,I am at a loss and I would really appreciate if someone helped me...
