Given the root node of a binary search tree (BST) and a value to be inserted into the tree, insert the value into the BST. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST. Note that there may exist multipl...
1/*2This look up is a fast operation because you eliminate the half3the nodes from your search on each iteration by choose to follow the4left or right of the sub-tree. In the worst case, you will know whether5the lookup was successful by the time there is only one node left to6sea...
If we have to insert an element 2, we will have to traverse all the elements to insert it as the left child of 3. Therefore, to performinsertionin a binary search tree, the worst-case complexity= O(n) whereas the time complexity in general = O(h). Suppose we have to delete the e...

The deleted node is then ignored during search and traversal operations. This can be useful in cases where we expect to delete and insert a lot of nodes in the tree, as it reduces the cost of modifying the tree structure. Here is an example of an optimized C++ implementation using lazy ...

This implies high memory footprint and slow operation, since the time complexity of a search or insert operation is proportional to the number of stored elements in most cases. We propose a special type of binary tree that overcomes both limitations within certain constraints....
Searching, insertion, and deletion in a balanced Binary Search Tree (BST) have an average time complexity of O(log n), where n is the number of nodes. In contrast, linked lists have O(n) time complexity for these operations. The logarithmic time complexity of BSTs can result in faster ...
