Complexity Analysis
Initialize a queue for BFS and a hash set for visited nodes.
Start with the root node, adding it to the queue.
While the queue is not empty, process nodes level by level.
For each level, iterate through the nodes from right to left.
For each node, check if its right child is in the visited set.
If the right child is visited, remove the node by setting its parent's reference to null.
If the right child is not visited, add it to the visited set and enqueue its children for the next level.
Continue until the queue is empty.
Return the modified root of the tree.
