Web12.2-6. Consider a binary search tree T T whose keys are distinct. Show that if the right subtree of a node x x in T T is empty and x x has a successor y y, then y y is the lowest ancestor of x x whose left child is also an ancestor of x x. (Recall that every node is its own ancestor.) First we establish that y y must be an ancestor of x x.
