Return the address of the node that precedes the specified `node` in an in‐order traversal of the binary tree to which `node` belongs, or the tree's rightmost node if `node` is the sentinel node of the tree. The behavior is undefined unless or `node` is a non‐leftmost member of a valid binary tree or is a sentinel `node`. Note that if the tree does not contain duplicate values, then the returned node will have the largest value less than that of `node`.
