Question: Consider a binary search tree T whose keys are distinct. Show that if the right sub tree of a node x in T is empty

Consider a binary search tree T whose keys are distinct. Show that if the right sub tree of a node x in T is empty and x has a successor y, then y is the lowest ancestor of x whose left child is also an ancestor of x. (Recall that every node is its own ancestor.)
