insertion的c++实现过程如下代码所示: /**insert(int key) is publically invoked, and the key could be inserted at proper position * *parameters: 1. key //the value of an node * *return void **/voidBST::insert(intkey){if(this->root != NULL) {//The BST has already intialized, so we...
Learn how to do deletion in a binary search tree using C++, its time complexity, and why deleting a node in BST is difficult.
If we make sure that height of the tree remains O(Logn) after every insertion and deletion, then we can guarantee an upper bound of O(Logn) for all these operations. The height of an AVL tree is always O(Logn) where n is the number of nodes in the tree....
Case 2:Deleting a node with two children: call the node to be deletedN. Do not deleteN. Instead, choose either itsinordersuccessornode or its inorderpredecessornode,R. Copy the value ofRtoN, then recursively call delete onRuntil reaching one of the first two cases. If we choose the in...
Now let's see the difference between the Red-Black tree and the AVL tree data structure, Even though, both red-black trees and AVL trees are the most commonly used balanced binary search trees and they support insertion, deletion, and look-up in guaranteedO(logN)time. ...
