Please fill the blanks in the RR rotation of AVL tree. struct AVLTreeNode { ElementType Element; struct AVLTreeNode *Left; struct AVLTreeNode *Right; int Height; }; typedef struct AVLTreeNode *Position , *AVLTree; Position SingleRotateWithRight( Position K2 ) { Position K1; K1 = K2->Right; Answer; K1->Left = K2; K2->Height = Max( Height( K2->Right ), Height( K2->Left ) ) + 1; K1->Height = Max( Height( K1->Right ), K2->Height ) + 1; return K1; /* New root */ }
