A hash table stores 32-bit positive integer keys n using the hash function n % M, where M is an odd prime number. Prove that for each bit position in the key, the two keys that differ only in that bit position will have different hash values.

5. Draw the hash table that results using the hash function: h(k)=kmod13 to hash the keys 18, 41, 22, 44, 59, 32, 31, 73. Assuming collisions are handled by Double hashing. ['M' is '7' which is less than the HTS and the hash function does not evaluate to '0'].
a. Suppose you are given the following set of keys to insert into a hash table that holds exactly 11 values: 113 , 117 , 97 , 100 , 114 , 123 , 116 , 98 , 99 using the hash function h(item) = item%11 Fill in the following hash table Reference: URL in the Hash tables item 113 is provided since 113%11 = 3 0 1 2 3 4 5 6 7 8 9 10 Hash(item) 113 item b....
A hash table is a data structure that supports the storage of subset of keys from a very large set S. To add a key x to a hash table, we use the hash function h: we compute h(x) and store x at location h(x). If two values x and y hash to the same location, we say we have a collision. For the hash table to work efficiently, we want to minimize the probability of collisions. The hash function...
5. Hashing (a) Consider a hash table with separate chaining of size M = 5 and the hash function h(x) = x mod 5. i. (1) Pick 8 random numbers in the range of 10 to 99 and write the numbers in the picked sequence. Marks will only be given for proper random numbers (e.g., 11, 12, 13, 14 ... or 10, 20, 30, 40, .. are not acceptable random sequences). ii. (2) Draw a sketch of the hash table...
Insert elements into a hash table implemented using chain hashing, as an array of linked list in which each entry slot is as a linked list of key/value pairings that have the same hash (outcome value computed using certain hash function). You are allowed to use “Hash Function”, h(k) = k % x where, x is the value you will need to decide to use, that you find appropriate for this implementation. The main requirements are the following: 1. Input:...
A positive integer is a prime number if its only positive integer divisors are itself and 1. Write a program to determine whether or not a given integer is prime. The program should contain two functions: main: to ask the user for a positive integer and to print the result isPrime: to determine whether the user's input is prime by testing all possible divisors. This function should return two values: variable_1: a Boolean value indicating whether the number is prime...
Demonstrate how you can construct an Iterative Hash h function using the Merkle- Damgard Design. Use as your compression function f:{0, 1}^v times {0, 1}^b rightarrow {0, 1}^v, AES with 512-bit keys. Explain what the values of v and b will be in your compression function and where in the block cipher (AES) are you using the blocks of the message you want to hash. Using the iterative hash function you just create above, show how a digest for a...
Explain each answer. Select the correct option for the following multiple choice questions or provide short answers accordingly: 1. Consider a hash table with chaining, of size N. Assume in each of the following scenarios the table starts empty. Further assume K pairs of <key, element> are added and K N Then, in which of the following situations will a find operation for a particular key have a potential worst-case runtime of O(N) a) The keys of all elements are...
You have a hash table of length 7 (tablesize 7). You are given a hash function f(x)-x % tablesize, where x is the value to be hashed and fix) is the hash address. Quadratic probing is used to resolve the collisions. The hash function receives the input 40, 26, 15, 12, 5, 17) in that order. Place each number in hash table in its correct address. The first two values are already placed in their correct positions If there isn't...
