Hey @mikkyimran
Try this once https://www.geeksforgeeks.org/bottom-view-binary-tree/
If you still need help, we’ll try something else and figure it out together.

@mikkyimran -1 doesn’t mean end of input. It just means NULL node. There is even a video at the end of the article. Try that for better understanding.
