Since the data is organized in a tree structure, the parent node has the links to its child nodes. If we want to search a record, we have to traverse the tree from the root through all its parent nodes to reach the specific record. Thus, searching for a record is very time consuming. The hashing function is used to locate the root. Neethi Ramaiah answered Oct 7, 2020 Neethi Ramaiah comment Share Follow See all 0 reply Please log in or register to add a comment.
