Deletion of node from binary search treec program

Copy the contents of the inorder successor of the node to be deleted and delete the inorder successor. The inorder successor can be found by finding the minimum element in the right subtree of the node.

Case 3: Node to be deleted is an internal node with one child. For this case, delete the node and move its child up to take its place. Skip to content.

If you have any doubt or any suggestions to make please drop a comment. Hi, in the full code for iterative approach, deletion of node with 2 children does not handle the 2nd case when successor is on the left subtree of the deleted node's right child.

I believe you left that part out. I had problem with deleting Node with 2 children and your guide helped me a lot. Thank you. Deleting a node in binary search tree Deleting a node consists of two operations- Search for the node that has to be deleted.

Delete the node once it is found. The node that has to be deleted is a leaf node has no children. The node that has to be deleted has one child. Write root.
