Questions for Hashing and Skiplists
(a) The next two questions relate to the following hashing setup table size is 11 elements . hash keys are lower-case alphabetic strings . the hash function is h(k) code(last Letter (k)) mod 1 1 Where last Letter extracts the last letter from its input and code returns an integer representing the position of the letter in the alphabet (starting at zero). So, for example h(anna) returns 0, h(mob) returns 1 and h(noon) returns 2...

4 Let the set of all possible keys considered is the set of all integers from 0 to 10,000 inclusive. Consider a closed hashing and a hash table of size M 10 and the hash function h(x) xmod 10. Note: Using a prime number as the size of the table is not a good idea. However, we do so to keep the calculations simple. a) Write an algorithm (using any programming language) to find the largest value in this hash...

Let 'M' denote the hash table size. Consider the following four different hash table implementations: a. Implementation (I) uses chaining, and the hash function is hash(x)x mod M. Assume that this implementation maintains a sorted list of the elements (from biggest to smallest) for each chain. b. Implementation (II) uses open addressing by Linear probing, and the hash function is ht(x) - (hash(x) + f(i)) mod M, where hash(x)x mod M, and f(i)- c. Implementation (III) uses open addressing by...

3. (20 points) In open addressing with double hashing, we have h(k,i) hi(k)+ih2(k) mod m, where hi(k) and h2(k) is an auxiliary functions. In class we saw that h2(k) and m should not have any common divisors (other than 1). Explain what can go wrong if h2(k) and m have a common divisor. In particular, consider following scenario: m- 16, h(k) k mod (m/8) and h2(k)-m/2 and the keys are ranged from 0 to 15. Using this hash function, can...
