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.

Consider a simple hash function as "key mod 8" and a sequence of keys as
75, 89, 42, 58, 94, 38, 32, 21. What will be the final sequence if you insert
those keys in an array of size 8 using linear probe.
A linear probing hash table of length 10 uses the hash function h(x) = x mod 10 + 1. mod is the reminder operator. For example the h(42) = 42 mod 10 + 1 = 2 + 1 = 3 so we insert 42 in the position 3 in the array.
After inserting 6 integer keys into an initially empty hash table, the array of keys is…
There is a hash table of size, m = 10,000. Use the classic Mid Square Method to findout the index of the hash table where the information for key k = 9452 will be stored
