A binary tree is made of nodes. Each node contains . a "left" pointer -- left child. a "right" pointer – right child. a data element.. The "root" pointer points to the topmost node in the tree. The left and right pointers recursively point to smaller. Yan Shi. CS/SE 2630 Lecture Notes. Partially adopted from C++ Plus Data Structure textbook slides. Review: Binary Search . in a Sorted .
