Java Sudoku Solver | Backtracking | Java Placement Course

hey if you are trying this code in leetcode it will throw "time limit exceeded" error.
and that is simply because we are using O(n^2) approach to check if the number is safe in the grid.(by using two for loops)
so instead,

if(board[(row/3)*3 + i/3][(col/3)*3 + i%3] == (char)number+'0')
return false;

use this, it does the same thing but in O(n) .
Happy Coding.

Didi, on basis of your video my Java course is depending.Because I am EE background and I only understand your videos bcz of your teaching techniques and root level explanations.
So it is my humble request, if possible then kindly upload videos regularly.

Thanks again for the root level explanations on each video.
