design hash table
Suppose you need to design a hash table. The keys themselves are (pointers to) C-style zero-terminating strings, so the string "foobar" occupies seven bytes. You are interested in minimizing the space used while keeping search time within reasonable bounds. You expect to store 1000 names with (on average) 7 letters each. If, for example, you choose separate chaining with 2000 buckets, the space required will be 24000 bytes: 8000 = (2000 buckets times 4 bytes per bucket...

Suppose we wish to allocate a hash table, with collisions resolved by chaining, to hold roughly n=1000 character strings and we don’t mind examining an average of 3 elements in an unsuccessful search. If we choose the division method to design the hash function: 1) What is the load factor? 2) What value of 'm' should be picked? (m is the number of slots in the hash table) Explain briefly why you pick this m.

Assume a Hash table has 7 slots and the hash function h(k) = k mod 7 is used. The keys 14, 3, 11, 6, 10, 4, 20, and 17 are inserted in the table with collision resolution by chaining. Assume that the keys arrive in the order shown. (a) Show the hash table obtained after inserting all 8 keys. [Show only the final table] (b) Under the assumption that each key is searched with probability 1/8, calculate expected number of...

Insert the numbers 10, 23, 52, 29, 8, 33, 27, 4, 17 and 6 into a hash table of size 11. Assume that the table is initially empty and uses chaining to resolve collisions. Use a simple division-based hash function. Draw the resulting hash table. (b) Search for the numbers 35, 41 and 18 in this hash table. For each number, how many hash table elements did you have to examine? (c) In an unsuccessful search in a hash table...

Exercise 3 (5 points). Suppose we have a hash table of m = 9 slots, and we resolve collisions by chaining. Demonstrate what happens when we insert the keys 5, 28, 19, 15, 20, 33, 12, 17, 10. Use the division-method hash function h (k) = k mod 9.

Suppose you have the following hash table, implemented using linear probing. The hash function we are using is the identity function, h(x) = x. 0 1 2 3 4 5 6 7 8 9 8 12 3 14 4 21 In which order could the elements have been added to the hash table? There are more than one correct answers, and you should give all of them. Assume that the hash table has never been resized, and no elements have...

#3 [3 points] Sketch a hash table of size N=11, where the hash function is hash(key) = key mod N and quadratic probing is used to resolve collisions, after the following elements are inserted: 20, 42, 45, 49, 62, 72, 95. The probes are based on this equation: (H+c1∗i+c2∗i2)mod(N) and c1=1, c2=1. If direct hashing was used to store the same elements as the previous problems (20, 42, 45, 49, 62, 72, 95), what should be the minimum size of...

2. (10 points.) The procedure HASH-SEARCH takes a hash table T[O : m-1) and a key k as its parameters. Each element of T is either a key or NIL. The procedure searches for k in T by probing. If it finds k, then it returns the index j where k appears in T. If it cannot find k, then it returns -1. (A procedure very much like HASH-SEARCH is discussed on pages 269–274 of Cormen.) HASH-SEARCH(T, k) i= 0...
