Also if you have any doubts, feel free to ask in comments, we will reach you ASAP.

Solution:

The complexity of deleting the root of a minimum-level BST with n nodes is O(logn).

Explanation:

The deletion of root is a iterative process involving two steps:

The first step involves getting the root
The next step is to pick one of the child elements and replace to root node.
his step goes on until we reach one of the leaf nodes.

So getting the root is O(1)

getting the child process O(1)

keep this repeating until we reach a leave node.
