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 is uniform in the sense that each key is equally likely to be hashed to any location in the table. Suppose we want to store 20 distinct keys into a hash table of size 100. What is the probability that there is no collision?

    0. Introduction. This involves designing a perfect hash function for a small set of strings. It demonstrates that if the set of possible keys is small, then a perfect hash function need not be hard to design, or hard to understand. 1. Theory. A hash table is an array that associates keys with values. A hash function takes a key as its argument, and returns an index in the array. The object that appears at the index is the key’s...

    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:...

    C programming Problem 3 [Set via Hashing] As mentioned in the lecture, a hash table can be used to implement a Set ADT. Let's try to use the template below to implement a Set with double hashing. Here we assume the Set contains names with 3 characters long. Since it is a Set, we do not need to have an explicit value for each key. We will use a token value of 1 if a name belongs to the Set....
