Binary search tree deletion in c
WebMar 7, 2024 · If the node to be deleted from the tree has no child nodes, the node is simple deleted from the tree since it is a leaf node. Step 1: The node to be deleted is 8. Step 2: Since the node 8 is a leaf node consisting of no child nodes, it is simply removed from the tree. The BST structure after deletion is shown as follows. 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. Following is the C++ program that demonstrates it:
