I am facing run errors in my code.
My remove function is working fine.
Please have a look at " constructBST " function.
I have highlighted it in the code.
Run errors : Delete Nodes from BST
your remove function is not working for the cases when you want to remove the root node in such a case your parent will be null and you try to access parent.left or parent.right then it will show null pointer exception.
run your code for this test case
