Assuming collisions are handied by Double hashing.
Explain how a hash table with linear probing collision handling works internally. Illustrate by showing a hash table containing the numbers 3, 11, 16, 22, with 7 hash buckets. (Assume that we just use the numbers themselves as hash values, i.e., our hash function for integers is hashCode(x) = x.)
b) Consider an empty hash table of size 7. Draw the table that results after inserting, in the given order, the following key values: {19, 26, 13, 48, 17} when collisions are managed and handled by double hashing method with function: h(k, i) = [h,(k) + i * hz(k)] mod 7, where h, (k) = k mod 7 and h, (k) = 5 – (k mod 5).

). This problem is about the chaining method we discussed in the class. Problem 3 (, Consider a hash table of size N = 11. Suppose that you insert the following sequence of keys to an initially empty hash table. Show, step by step, the content of the hash table. Sequence of keys to be inserted:
Consider a hash table of capacity 4 that uses open addressing with linear probing. This hash table uses a hash function that takes the remainder when the hash code of a string is divided by the capacity of the hash table. (For example, "air" hashes 0.) The hashCode method has been overridden for strings, which simply returns 0 if a string begins with 'a', 1 if it begins with 'b', etc. /** Returns 0 if a String begins with 'a', 1 if it begins with 'b', etc. */ public int hashCode() { return this.charAt(0) - 'a'; } Assume that "apple", and "cherry" have been inserted in this order into the hash table. "guava" is to be inserted into the hash table. (a) Which array slot/index should "guava" be placed? Answer: (b) What is the load factor after "guava" is inserted into the hash table? Answer:
Select all explicit instructions that apply to the following prompt: Implement an open addressing hash table to store a list of integers. Your task is to handle collisions using open addressing and implement basic operations such as insertion, deletion, and searching. The open addressing technique you will use is linear probing.
