While traversing if key == root->value, we need to delete this node: If the node is a leaf, make root = NULL. If the node is not a leaf and has the right child, recursively replace its value with the successor node and delete its successor from its original position. WebMar 19, 2024 · Search. A recursive algorithm to search for a key in a BST follows immediately from the recursive structure: If the tree is empty, we have a search miss; if the search key is equal to the key at the root, we have a search hit. Otherwise, we search (recursively) in the appropriate subtree. The recursive get() method implements this … dewey\\u0027s reflective thinking process
