- Q6) Answer the following: [2 Marks] a) Write a small code fragment that generates a random integer number using Random class . b) How do you check whether a given key is contained in a map? (Give a Java code example.) c) Create a class MapTester. In it, use a HashMap to implement a phone Book. In this class, implement two methods: public void enterNumber(String name, String number) public String lookupNumber(String name) The methods should use the put and get methods of the HashMap class to implement their functionality' make a hashmap ' import hashlib import sys def insert (hashmap, key, value): ' insert a key value pair into the hashmap ' hashmap[key] = value def remove (hashmap, key): ' remove a key value pair from the hashmap ' del hashmap[key] def search (hashmap, key): ' search for a key in the hashmap ' if key in hashmap: return hashmap[key] else: return None def print (hashmap): ' print the hashmap ' for key in hashmap: print (key, ":", hashmap[key]) 'end of print' def main (): 'make a menu that lets the user call the functions' hashmap = {} while True: print (""" Menu: 1. Insert 2. Remove 3. Search 4. Print 5. Quit """) choice = input ("Enter your choice: ") if choice == "1": key = input ("Enter the key: ") value = input ("Enter the value: ") insert (hashmap, key, value) elif choice == "2":…In java Create a hash table using an array with elements 324,221,563,679,234,569,890,5678,654 then perform the following operations. 1) Insert 227 2) Delete 679 and Insert 9 3) Insert 67 4) Display the hash table content Note: This hash table uses technique linear probing when encounters a collision.
- Question1- Add to the Test class a method called isSubSet(LinearProbingHashTable h1, LinearProbingHashTable h2) that is receives 2 hash tables h1 and h2, and returns true if h1 is sub set of h2, otherwise the method returns false. Don't forget to test the method in the main of Test classWhich of the following statements are true about a HashSet ? Select all that apply. Hint: you should be able to answer this question based only on the material presented in class. If E inherits Object.hashCode(), then there will be no collisions. A HashSet iterator should iterate through the Hashset elements in the order in which they were added to the Hashset. Two HashSets are equal (according to the equals() method) if they have the same size and their elements can be paired such that the pairs are equal according to the E.equals() method. OA HashSet could be implemented using a HashMap namely the key is the same as the value.Java Code: Add a HashMap to your Lexer class and initialize all the keywords. Change your lexer so that it checks each string before making the WORD token and creates a token of the appropriate type if the work is a key word. When the exact type of a token is known, you should NOT fill in the value string, the type is enough. For tokens with no exact type we still need to fill in the token’s string. Rename “WORD” to “IDENTIFIER”. Strings and characters will require some additions to your state machine. Create “STRINGLITERAL” and “CHARACTERLITERAL” token types. These cannot cross line boundaries. Your lexer should throw an exception if it encounters a character that it doesn’t expect outside of a comment, string literal or character literal. Create a new exception type that includes a good error message and the token that failed. Ensure that the ToString method prints nicely. Add “line number” to your Token class. Keep track of the current line number in your lexer and populate each…
- HashSet Iterator Example : How To Iterate Through A HashSet/Set2) Hash Innards Homework • Unanswered Select all true statements from the below. Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation. SHOW MORE V a A hash function takes a key and produces an index into the hash table. The next step in this process is often something like 'h%SIZE' so that the hash value of the key will fit within the table b (having SIZE elements, you see). Common techniques involve exclusive or of bits within the key and folding different sections of bits within the key into each other. The best hash method for character strings is to simply add up the ASCIlI values of their individual characters. Coming up with a perfect hash for a given set of keys can be a difficult and time-consuming task.Use C++ Programming language. The header file below defines a class for a simple hash table: hashMap.h Download hashMap.h Write a driver program to test the class with the following data: (520, "3100 Main St, Houston TX "); (37, "2200 Hayes Rd, Austin TX"); (226, "1775 West Airport St, San Antonio TX"); (273, "3322 Walnut Bend, Houston TX"); (491, "5778 Alabama, Waco TX"); (94, "3333 New St, Paris TX"); Make sure to test the find function for exiting and non-existing data 2. Modify the type of member key in class HashEntry from int to a string (this is useful is the key is e.g. the phone number or e-mail address). Use the string hash function discussed in class (see ppt notes) or search online for alternative functions that work on strings. 3. Modify the collision strategy of class HashMap to do separate chaining instead of linear probing. Be sure to modify the display function so that items in the bucket chains are also displayed in a pre-defined order…
- . Write a code using the following hints and apply HashMap<K, V> and its methods get and put for public class CourseInformation (i) Create a HashMap object called Course to add a key and its value. //Key is your course name and value is your course code. (ii) Use put method to map a course name with the course code. // add any FOUR COURSE NAMES WITH ITS COURSE CODE which are represented as a String (iii) Use get method to find the course code for any one of the course.struct insert_into_hash_table { // Function takes a constant Book as a parameter, inserts that book indexed by // the book's ISBN into a hash table, and returns nothing. void operator()(const Book& book) { ///// /// TO-DO (8) ||||. // Write the lines of code to insert the key (book's ISBN) and value // ("book") pair into "my_hash_table". /// END-TO-DO (8) // } std::unordered_map& my_hash_table; };Exercise 3 - Simple hash table Develop a simple hashtable with specified size (parameter) that accepts key-value pairs and stores them in an internal structure. ● • The key has to be a string ● ● Use your hash function from exercise 2 • The value can be an object Demonstrate how your hashtable works with multiple inputs Implement add (key, value), get(key), and print () methods
