Why use binary search trees when hash tables exist?

WebLike a hash table, a binary search tree is a method of storing keys for later retrieval and manipulation. Both have their own strengths, and the best storage type to use is dependent on what tasks are going to be undertaken with the data being stored. If the primary tasks needed are search, insert, or delete, a hash table performs them in O (1 ... WebA list is acceptable to use as a table entry because while traversal is O(n), the lists tend to be short assuming the hash table is sufficiently large and the objects stored in the table are hashed using a good quality hashing algorithm.
