An advantage of chained hash table (external hashing) over the open addressing scheme is
(A) Worst case complexity of search operations is less
(B) Space used is less
(C) Deletion is easier
(D) None of the above
In Open Addressing scheme sometimes though element is present we can't delete it if empty bucket comes in between while searching for that element. External hashing scheme is free from this limitations . Hence, Option c is correct answer.
