suppose both trees contains n nodes then converting to dll both the trees O(n) + O(n) then merging two dll's O(n) converting back to tree also O(2*n)=O(n)......// not sure about it
code for converting tree to dll node * bsttolist(node *root){ if(root==NULL) return NULL; node *l=bsttolist(root->left); node *r=bsttolist(root->right); root->left=root; root->right=root; append(l,root); append(l,r); return l; } here append function merges two circular doubly linked lists , you can make that on your own On Mon, Jul 26, 2010 at 5:52 PM, Manjunath Manohar <manjunath.n...@gmail.com > wrote: > @jalaj: could u pls elaborate on that a bit more..will it have the > complexity of O(n logn logn), and also can u provide the pseudocode pls.. > > -- > You received this message because you are subscribed to the Google Groups > "Algorithm Geeks" group. > To post to this group, send email to algoge...@googlegroups.com. > To unsubscribe from this group, send email to > algogeeks+unsubscr...@googlegroups.com<algogeeks%2bunsubscr...@googlegroups.com> > . > For more options, visit this group at > http://groups.google.com/group/algogeeks?hl=en. > -- With Regards, Jalaj Jaiswal +919026283397 B.TECH IT IIIT ALLAHABAD -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
