Hey, i understood the code for this problem, but unable to feel where exactly backtracking is working. Please explain me, due to which part of this code, backtracking happens?
There’s no explicit “undoing” step here, but each time the function is called for some index “i”, out[i] is getting overwritten and that’s how different outputs are being obtained.
I hope I’ve cleared your doubt. I ask you to please rate your experience here
