Program Plan Intro

Open Addressing:

  • Open Addressing is a method of finding an open location in the hash table at the time of collision.
  • There are several variations for open addressing such as linear probing, quadratic probing, and double hashing.

Quadratic Probing:

  • Quadratic probing is one other variation of open addressing.
  • It is introduced to avoid the clustering problem in linear probing.
  • Quadratic probing will look at the cells at indices (k + j2) % n, for j ≥ 0, i.e., k, (k + 1) % n, (k + 4) % n, (k + 9) % n, ..., and so on.
  • Starting from the initial index, quadratic probing will add an increment of 2 to k to define a search sequence.

I need help with this question, please. Parts A and B A.) Add the following numbers to an 11-entry hash table using linear probing to resolve collisions.  Stop before adding an item that would result in α > 0.75. This means you might not use all the numbers.  (Spoiler alert: you won't use them all.) 39 68 60 71 83 52 99 55 49 77 58 26 76 66 37 28 For the hash function, simply take the number mod the table size. In 11 blanks, write the number that would end up at that entry in the table.  If there is no number at that location, write empty. B.)  Add the following numbers to a 23-entry hash table using linear probing to resolve collisions.  Stop before adding an item that would result in α > 0.75.  This means you may not use all the numbers.  39 68 60 71 83 52 99 55 49 77 58 26 76 66 37 28 For the hash function, simply take the number mod the table size. In 23 blanks, write the number that would end up at that entry in the table.  If there is no number at that location, write…
Insert keys {10, 22, 11, 31, 24, 88, 38, 21} into an empty hash table with CAPACITY = 10 using quadratic probing (c1=0 and c2=1) to resolve collision (You shouldn't use a for/while loop except to increment the value of i for quadratic probing). Use the hash function is h(k, i) = (h’(k) + c1* i + c2* i^2) mod 10 and h’(k) = k mod 10.
Does a hash table of size m always have the same number of linked lists? I've been trying to understand the function of a hash function, but I just can't seem to get it. Give a case study to demonstrate your point.
