rehashing occurs when a hash table becomes too full and we must migrate to a larger table. if we have N elements, and our new tables size is M, what is the big-O time of rehashing?

A. O(M)

B. O(N+M)

C. O(N)

D. O(M log N)

Answer #1

It should be O(N+M) because O(N+M) is for assigning memory and assigning records to new hash table

    Dynamic Tables Analysis - Whenever the array becomes full, creates a new larger array and copies all elements to it. Instead of doubling the size, changes the size from n to n + ⌈√n ⌉. This way, the amount of wasted space is O(√n) instead of O(n). What is the total running time for a sequence of n Increment-Sizes, starting with an array of size 1? Express your answer using notation.

    Hash Tables. (Hint: Diagrams might be helpful for parts a) and b). ) When inserting into hash table we insert at an index calculated by the key modulo the array size, what would happen if we instead did key mod (array_size*2), or key mod (array_size/2)? (Describe both cases). Theory answer Here Change your hashtable from the labs/assignments to be an array of linkedlists – so now insertion is done into a linkedlist at that index. Implement insertion and search. This...

    3. (03] (10 pts) We are to design a hash table for n = 1000 elements. On average, suc- cessful searches should require no more than 2 element examinations and unsuccessful searches should examine no more than 8 elements. Assuming that we have a simple uniform hash function that uses the division method, what is the minimum hash table size if we use chaining? Assume that each element takes 10 bytes of storage and each pointer takes 4 bytes.
