c++ Programming Glossary: n2how to merge two BST's efficiently? http://stackoverflow.com/questions/1008513/how-to-merge-two-bsts-efficiently into the other... Complexity of this method being O n1 log n2 .. where n1 is the no of nodes of the tree say T1 which we have.. no of nodes of the tree say T1 which we have splitted and n2 is the number of nodes of the other tree say T2 ... after this.. T2 ... after this operation T2 is the only BST that has n1 n2 nodes... My question is..Can we do any better than O n1 log..
