Problem 1: After inserting 13 elements into a hash table the result looks as in Figure ??. Being a good student, you realize this is a problem. (i) What is the problem here? (ii) Give an example of a hash function that could give rise to this behavior. (iii) What would be a better hash function? 0123 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 0+ →→2131 → 2 → 30 33 63 15 266 388 Slika 1: Hash table. 1

The Java hash function for Strings computes a hash code based on a fixed maximum number of characters of the string. Given that Strings have no meaningful upper bound in length, describe how an effective, constant-time hashing algorithm can be constructed. (Hint: If you were to pick, say, eight characters to represent a string of length l, which would you choose?)

Implement a commonly used hash table in a program that handles collision using linear probing. Using (K mod 13) as the hash function, store the following elements in the table: {1, 5, 21, 26, 39, 14, 15, 16, 17, 18, 19, 20, 111, 145, 146}.

Rehash the hash table below (separate chaining, length 5) to a new length of 10. Draw the new hash table after rehashing, Assume that hashCode (x) = x for this question. Assume that we always traverse a chain from head to tail and always insert at the head of the chain example 0:15->30 1:6->21->11 2: 3: A 4:-14

Use the hash function h(x) =x mod 11 to load the following values 25, 14, 36, 47 using separate chaining.

How can a hash table provide more efficiency than a linear list? What may the issue be? The deployment of a hashtable

Does a hashing of size m always contain the same number of linked lists? Hash functions make no sense to me at all. Provide an illustration to back up your claims.

A poorly constructed hash map has resulted from carelessly grouping all the data together (that is, they are all in the same LinkedList). You should elaborate on why this is counterproductive to using a hash map.

We have a poorly-designed hash map where all of the stored values are in one bucket (meaning they're all in one Linked List). Explain why this undermines the advantages of a hash map.

As compared to a linear list, how can the efficiency of employing a hash table as an alternative be improved? What might possibly be the problem?its creation by the application of a hashtable

Is there a hash table that can handle linked lists of length m? What are the goals of using a hash function? Give an example.
