4. fast please If h ( x ) = x mod 7 (i.e. the hash table has 7 rows) and separate chaining resolves collisions, what does the hash table look like after the following insertions occur: 5, 8, 10, 24, 15, 32, 17, 14, 19, 38? Assume that each node item contains only a search key for its data. Draw the FINAL representation of the hash table clearly
You're tracking information on rocket launches. Each launch is assigned a number from 1000 to 100000. There will probably be around 5000 launches, and you're using a hashing algorithm that divides the highest possible number of launches by the expected number of launches. What is the hashing algorithm key in this situation? a. 200 b. 20 c. 500000 d. 5000000
All of these statements are related to hash function, hash table.
= Question 3. In the following hash table, we insert elements using hashing with open addressing with quadratic probing. Elements have as keys integer numbers, and the hash function for the i-th probe is given by hash(x, i) (x + ²) %11. We insert, in the given order, the elements with the following keys: 46, 58, 57, 39. Indicate, where these elements will be placed in the table. index value 0 1 2 3 4 5 6 7 8 9 10
In our subpar hash map, we store each value in a single container. In this case, a hash map was able to achieve its intended result.

Task - 1: Write a java program to implement the following algorithms for Open Addressing techniques for Hash Table data structure. (Use a simple array of integers to store integer key values only). HASH-SEARCH(T, k) HASH-INSERT (T, k) i = 0 repeat j = h (k, i) if T[j] == NIL T[j] = k return j else i = i + 1 ● i = 0 repeat until i == m error “hash table overflow" For both algorithms, to compute the index j, write the following methods: getLinear ProbIndex (key, i) getQuadraticProbIndex ● get DoubleHash (key, i) (key, i) j = h (k, i) if T[j] == k return j i = i + 1 until T[j] == NIL or i = m return NIL Linear Probing index is computed using following hash function: h(k, i) = (h₁(k) + i) mod m h₁(k)= k mod m Quadratic probing index is computed using following hash function: h(k, i) = (h₁(k) + i²) mod m h₁(k)= k mod m Double hashing index is computed using following hash function: h(k, i) = (h₁(k) + i h₂(k)) mod m h₁(k)= k mod m h₂(k) = 1 + (k mod m - 1)
