Binary Search Tree in C - CodesDope

WebThis is a C Program to perform deletion in binary search tree. The important thing to note is, inorder successor is needed only when right child is not empty. In this particular case, inorder successor can be obtained by finding the minimum value in right child of the node. Here is source code of the C Program to Perform Deletion in a BST. WebRecursive Solution. The idea is to traverse the tree in a postorder fashion and delete the left and right subtree of a node before deleting the node itself. Note that we cannot traverse a tree in preorder or inorder fashion as we can’t delete a parent before deleting its children.

WebDec 17, 2024 · If key < root -> value, recursively traverse the left subtree. 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. WebHere we will use recursion to delete all nodes of a binary tree one by one. We will traverse the tree by using post Order traversal because we have to delete all child nodes first before deleting root node. If we delete root node first then we cannot traverse child nodes of root without maintaining a separate data store. Let "root" be the ...
