WebAug 3, 2024 · BST Removing Element Recursively Removing an element from a BST is a little complex than searching and insertion since we must ensure that the BST property is conserved. To delete a node we need first search it. Then we need to determine if that node has children or not. If no children - Just delete. If a single child - Copy that child to the node.
