WebSo overall time complexity will be O (log N) but we will achieve this time complexity only when we have a balanced binary search tree. So time complexity in average case would be O (log N), where N is number of nodes. Note: Average Height of a Binary Search Tree is 4.31107 ln (N) - 1.9531 lnln (N) + O (1) that is O (logN). WebApr 7, 2024 · Deletion from a Binary Search Tree in Java. Deletion is a relatively complicated task than insertion, this is because deletion depends on the node that needs to be deleted. If the node to be deleted has no children (means, it is a leaf) then it can be easily removed from the tree.
