Backtracking
The Cursed Grid
Fill the cursed sudoku one square at a time. Hit a dead end? Erase and go back.
Loading the fight…
How to beat it
Go to the first empty square and try the smallest number that breaks no rule, then move on to the next. When nothing fits, erase, go back one square and try its next number. Bad branches die early, so the search stays small.
Now the real boss
Interviews ask for the code. Watch it run, then write it yourself, tested in Python, C++ or Java.
