... data structures in computing—trees. Tree structures are indeed a breakthrough in data organization, for they allow us to implement a host of algorithms much faster than when using linear data ... empty binary tree. Starting from this empty tree, we can build any binary tree by creating the first node with method addRoot and repeatedly applying the insertLeft and insertRight methods and/ or ... binary tree. This interfaces extends Position, thus inheriting method element, and has additional methods for setting the element stored at the node (setElement) and for setting and returning...
