- Write a function that is passed an array of numbers and returns a hash table containing the minimum, maximum and average value. @{min=????; max-???; average=???} Test by passing the function 3 different arrays of randomly generated numbers. If the array is empty set all 3 values to zero. (3)fast please c++ Insert the elements of A in hash table H of size 10. H is a vector of int is size 10. Do not allow duplicates. Draw the table. The hash function is the number itself; f(n) = n%10MyArrayList is defined inListing24.2. Write a program that generates 1000000 random double valuesbetween 0 and 999999 and stores them in a MyArrayList and in a MyHashSet.Generate a list of 1000000 random double values between 0 and 1999999. Foreach number in the list, test if it is in the array list and in the hash set. Run yourprogram to display the total test time for the array list and for the hash set.
- Exercise 3 - Simple hash table Develop a simple hashtable with specified size (parameter) that accepts key-value pairs and stores them in an internal structure. ● • The key has to be a string ● ● Use your hash function from exercise 2 • The value can be an object Demonstrate how your hashtable works with multiple inputs Implement add (key, value), get(key), and print () methodsC++ Design a HashMap without using any built-in hash table libraries. Implement the MyHashMap class: MyHashMap() initializes the object with an empty map. void put(int key, int value) inserts a (key, value) pair into the HashMap. If the key already exists in the map, update the corresponding value. int get(int key) returns the value to which the specified key is mapped, or -1 if this map contains no mapping for the key. void remove(key) removes the key and its corresponding value if the map contains the mapping for the key. Example 1: Input ["MyHashMap", "put", "put", "get", "get", "put", "get", "remove", "get"] [[], [1, 1], [2, 2], [1], [3], [2, 1], [2], [2], [2]] Output [null, null, null, 1, -1, null, 1, null, -1]Class HashTable: Implement a hash table to store integers (including negative ones). stored in the table int[] data. Use the hash function: h(x) = (x · 701) mod 2000. The table size is 2000. Ensure non-negative indices between 0 and 1999. Implement the following methods: insert(int key): Inserts the integer into the table. Returns true if successful, false if the element is already in the table. search(int key): Searches for the integer in the table. Returns true if found, false otherwise. delete(int key): Deletes the integer from the table. Returns true if successful, false otherwise. Class HashTable2: Implement a second hash table using a different hash function and collision resolution strategy. Keys are integers (including negative ones). Use the hash function: ℎ(�)=(�⋅53)mod 100h(x)=(x⋅53)mod100. The table size is 100. Ensure non-negative indices between 0 and 99. Implement the following methods: insert(int key): Inserts the integer into the table. Returns true if…
- = 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 9 102) Hash Innards Homework • Unanswered Select all true statements from the below. Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation. SHOW MORE V a A hash function takes a key and produces an index into the hash table. The next step in this process is often something like 'h%SIZE' so that the hash value of the key will fit within the table b (having SIZE elements, you see). Common techniques involve exclusive or of bits within the key and folding different sections of bits within the key into each other. The best hash method for character strings is to simply add up the ASCIlI values of their individual characters. Coming up with a perfect hash for a given set of keys can be a difficult and time-consuming task.#7.
