- 22 Consider a hash table with size m=7, fill the following items in the table if the hash function used is (6k-5) mod m. AAB, ABA,CDF,STW,YZQ,PFG (ASCII code) . Then count the number of collisions and solve the collision ( if possible) using one of the methods studied2. Implement the hash table for the following elements: a. 22,32,45,67,89,9 Use Double hashing technique to handle the collision. [ hash1(key)=key%10, hash2(key)=PRIME- (key%PRIME) ].Like numbers, strings can also be used as keys in a hash functions. A hash function for any string s = “abc” can be defined as: Hash(abc) = (a + b + c) % tableSize Consider the following ASCII table for different alphabets and use the hash function to create a hash table of 10 slots for the following Names using Open addressing (Linear probing to resolve collision). Names: ahmed, samir, saad, yazeed, raed, sultan, salman, azzam, saleh, hamad.

- In §12.2 Lamport's Hash we mentioned the notion of using only 64 bits of the hash. At each stage, 128 bits are computed, 64 bits are thrown away, and the hash of the retained 64 bits is used in the next stage. The purpose of only using 64 bits is so that a human does not need to type as long a string. Assuming the person will still only type 64 bits, does it work if hashn does a hash of all 128 bits of hashn-1, but what the person actually transmits is 64 bits of the result?2. Suppose that a computer has only the memory locations 0,1,2,...,19. Use the hashing function h where h(x) = (x + 5) mod 20 to determine the memory locations in which 57, 32, and 97 are stored.1. For the input 30, 20, 56, 75, 31, 25 and hash function h(K) = K mod 12 First, a. construct the open hash table.b. find the largest number of key comparisons in a successful search inthis table.c. find the average number of key comparisons in a successful searchin this table Second, a. construct the closed hash table.b. find the largest number of key comparisons in a successful search inthis table.c. find the average number of key comparisons in a successful searchin this table.
- in this code: def insertSort(A): for i in range(1,len(A)): j = i-1 while A[j]>A[j+1] and j>=0: A[j],A[j+1] = A[j+1],A[j] j -= 1 A = [3,1,11,9,10,2] insertSort(A) print(A) 1) What is the Hypothesis? 2) What is Your InductionUse the following values to answer the questions bellow: 66 47 87 900 126 140 145 500 177 285 393 395 467 566 620 735 Store the values into a hash table with 25 positions, using double hashing as the method of collision resolution. Use key % table size as a hash function, and (key + 3) % table size as the rehash function.PYTHON Why am I getting an error and it doesn't show the right output? Problem 1# Implement a hashtable using an array. Your implementation should include public methods for insertion, deletion, and# search, as well as helper methods for resizing. The hash table is resized when the loadfactor becomes greater than 0.6# during insertion of a new item. You will be using linear probing technique for collision resolution. Assume the key to# be an integer and use the hash function h(k) = k mod m where m is the size of the hashtable. class HashTableProb: def __init__(self, size=10): # Initialize the hashtable with the given size and an empty array to hold the key-value pairs. self.__size = size # size of the hashtable self.__hashtable = [None for _ in range(size)] self.__itemcount = 0 # Keeps track of the number of items in the current hashtable def __contains__(self, key): return self.__searchkey(key) def __next_prime(self, x): def…
- 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- In class HashTable implement a hash table and consider the following:(i) Keys are integers (therefore also negative!) and should be stored in the tableint[] data.(ii) As a hash function take h(x) = (x · 701) mod 2000. The size of the table istherefore 2000. Be careful when computing the index of a negative key. Forexample, the index of the key x = −10 ish(−10) = (−7010) mod 2000 = (2000(−4) + 990) mod 2000 = 990.Hence, indices should be non-negative integers between 0 and 1999!(iii) Implement insert, which takes an integer and inserts it into a table. Themethod returns true, if the insertion is successful. If an element is already inthe table, the function insert should return false.(iv) Implement search, which takes an integer and finds it in the table. The methodreturns true, if the search is successful and false otherwise.(v) Implement delete, which takes an integer and deletes it form the table. Themethod returns true, if the deletion is successful and false otherwise.(vi)…Computer Science insert 5 numbers using hashing and h(x) = k mod 11. d(x)=5 - k mod 5
