Question

Implement a hash table using linked version chaining. Complete code please

Explanation / Answer

When you enter a key and the hash function produces a location at which there is chaining, how does it determine which value in the linked list at that location belongs to that specific key, as opposed to another key involved in the collision? You just resort to linear search of the bucket by key. You may appreciate the following mini hash table implementation written in F#, taken from this blog post: > let hashtbl xs = let spine = [|for _ in xs -> ResizeArray()|] let f k = spine.[k.GetHashCode() % spine.Length] Seq.iter (fun (k, v) -> (f k).Add (k, v)) xs fun k -> Seq.pick (fun (k', v) -> if k=k' then Some v else None) (f k);; val hashtbl : seq -> ('a -> 'b) when 'a : equality This hashtbl function takes an association sequence xs of key-value pairs, builds a hash table represented as a spine array of ResizeArray buckets and returns a lambda function that finds the appropriate bucket and does a linear search in it for the given key k. The linear search is performed using the Seq.pick function.
