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
