Delete entire binary search tree
WebDec 4, 2024 · 3. I don't believe that asking for an entire function is okay. Therefore, here is an idea: first, find the node you want to remove. If the node has no children, just remove it. If the node has a left child, find it's maximum, delete it from the subtree and replace that maximum instead of the given node. Else (if the node has the right child ... 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 ...

WebOct 12, 2012 · How ever simplest will be set root node to null and let garbage collector do its job which will be O (1) rather than O (n) in above case.. This method will be O (n), when n = number of elements in the tree. By setting treeRoot = null, it will be O (1), as per the Java GC algorithm. @LuiggiMendoza I have mentioned that as the best way. WebMar 8, 2014 · I have simple binary search tree class with instance variable of type Node which is the root.

WebJun 22, 2024 · I've been trying to implement Deletion in a Binary Tree. I know that the three steps are: Identifying the node to be deleted and the deepest node. Replacing its data with the data of the deepest node. Deleting the deepest node. I had to traverse the entire tree to find the deepest node. In order to delete that node, I need to find its parent.
