WebTree structure: "one-to-many" relationship, except for the root node, there is only one direct predecessor, and all nodes can have 0 or more direct successors. Graph structure: "many-to-many" relationship, multiple immediate predecessors and multiple immediate successors. 2. Storage structure. Sequential storage (one-dimensional array) WebSuffix Tree Representations Suffix trees may have Θ(m) nodes, but the labels on the edges can have size ω(1). This means that a naïve representation of a suffix tree may take ω(m) space. Useful fact: Each edge in a suffix tree is labeled with a consecutive range of characters from w. Trick: Represent each edge labeled with a
