Both hash functions must hash the same type of keys. Double hashing boils down to linear hashing, except for the fact that the constant is unknown …
WebCuckoo sequence program or Cuckoo Hashing is a method used to solve the problem when a collision occurs in a Hash Table. Collisions are likely of two hash values of a hash function in a table. A collision occurs when two hash values for the same key occurs in the hash function of a table. To resolve that collision we use Cuckoo Hashing.
