Deletion in a binary search tree can be divided into three cases: The node to be deleted is a leaf node: If the node to be deleted is a leaf node, it can simply be removed from the tree. The parent node of the deleted node must have its corresponding child pointer set to NULL to...

Basically, the deletion can be divided into two stages: Search for a node to remove. If the node is found, delete the node. Note: Time complexity should be O(height of tree). Example: root = [5,3,6,2,4,null,7] key = 3 5 / \ 3 6 / \ \ 2 4 7 Given key to delete is ...
