Is cuckoo hashing good?

However, because of its worst case guarantees on search time, cuckoo hashing can still be valuable when real-time response rates are required. One advantage of cuckoo hashing is its link-list free property, which fits GPU processing well.

What is the complexity of hashing in best and worst case?

Hashing is the solution that can be used in almost all such situations and performs extremely well compared to above data structures like Array, Linked List, Balanced BST in practice. With hashing we get O(1) search time on average (under reasonable assumptions) and O(n) in worst case.

What is the worst-case time complexity of lookup for Cuckoo Hashing?

O(1)
● Cuckoo Hashing Hashing with worst-case O(1) lookups.

What is the worst-case efficiency of a lookup in a hash table using chaining?

O(n)
The worst-case running time is O(n), though, if all the elements end up put into the same bucket.

Which of the following is not a technique to avoid a collision?

Which of the following is not a technique to avoid a collision? Explanation: On increasing hash table size, space complexity will increase as we need to reallocate the memory size of hash table for every collision. It is not the best technique to avoid a collision.

What is worst case for hash table?

The worst-case performance of a hash table is the same as the underlying bucket data structure, (O(n) in the case of a linked list), because in the worst case all of the elements hash to the same bucket.

What is the worst-case complexity of a remove operation in cuckoo hashing?

If a key exists, it will be stored in its original bucket, either in the first array or the second one. In other words, at most two lookups are needed to figure out if the key exists or not, thus the worst-case complexity is O(1).

Which of the following is not hashing function method?

Probe Method is not used for hash function. Hash function is a function which, when applied to the key, produced an integer which can be used as an address in a hash table.
