Extendible hashingis a type of hash system which treats a hash as a bit string, and uses a trie for bucket lookup.Because of the hierarchal nature of the system, re-hashing is an incremental operation (done one bucket at a time, as needed).

A stack data structure can be implemented by using a linked list data structure. The stack implemented using linked list can work for an unlimited number of values. That means, stack implemented using linked list works for the variable size of data. So, there is no need to fix the size at the beginning of the implementation.
