Does a hash table exist that can handle linked lists of length m? What goals do you hope to achieve by using the hash function? Give an instance.
How may efficiency be increased when using a hash table instead of a linear list? What may be the issue?its formation via the use of a hashtable
The Java hash function for Strings generates a hash code based on the string's maximum length. Given that Strings have no meaningful length limit, describe how an effective, constant-time hashing method can be built. (Hint: Which of the following eight characters would you use to represent a string of length l?)

How is a hash table more efficient than a linear list? What's wrong?Its development used a hashtable.
you can search a hashtable either by the keys , or by the assiocated values. True or false ?
One way to potentially reduce the complexity of computing the hash code for Strings is to compute it only once—when the String is created.Future hashCode calls would return the precomputed value. Because the value of a String never changes, this has the potential to be useful. How would you rate the efficacy of such a method?
Trace Linear Probing with My Data A The hash table is size 7 and uses open addressing and linear probing. The hash function is hashCode(phone number) = last four digits % table size 555-1432 VoterA 555-6135 VoterB 555-2747 VoterC 555-6118 VoterD 555-5733 VoterE 555-4722 VoterF 555-7523 VoterG Show the hashCode of each Voter. Show the table after inserting the above voters in the listed order. Assume you want to retrieve each voter. How many seeks does it take to find each voter? How many seeks would it take to know that 555-5357 VoterH is not in the table? What does the table look like if you remove VoterF? Now how many seeks does it take to know that 555-5357 VoterH is not in the table? How many seeks does it take to retrieve voter G?
