... because finding the index of an element in a linked list requires searching through the list incrementally from its beginning or end, counting elements as we go. For instance, we could define a ... by their indices is called an array list (or vector, using an older term). Since our index definition is more consistent with the way arrays are indexed in Java and other programming l...

... 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 inser...
