Write a code in python, You will implement Hashtable using two techniques: Separate Chaining and Linear Probing.   Implement Hashtable using Separate Chaining Implement hashtable using Linear Probing Test your both Hashtable classes with instances of Student class; you can have three (3) data members and appropriate functions, including hash() function. Test your both Hashtable classes with instances of Employee class; you can have three (3) data members and appropriate functions, including hash() function.

Let's assume that a player plays a multi-agent game where, every gun has a  type: "Sidearms" or "Rifles" or "Sniper Rifles". Here, in every dictionary inside the tuple, the key is the gun name, the  first index of the dictionary value is the gun type and the second index of  the dictionary value is the kills done by that gun in a certain match. Now, write a Python program that will generate a dictionary from the given  tuple of dictionaries: ================================================ Given Tuple 1: ({"Ghost"   : ["Sidearms", 3]}, {"Vandal"  : ["Rifles", 15]}, {"Sheriff" :  ["Sidearms", 5]}, {"Operator": ["Sniper Rifles", 7]}, {"Phantom" :  ["Rifles", 10]}) Sample Output 1: {"Sidearms" : ["Ghost","Sheriff", 8], "Rifles" : ["Vandal", "Phantom",  25], "Sniper Rifles" : ["Operator", 7]} Explanation1: Here, in the expected dictionary the keys will be the type of the guns and  the values for an individual key will have the gun names and the sum of the  kills by those guns in a…

Modify the generic Pair.java class in two ways: Make it so that both values have the same type Add a method swap that swaps the first and second elements of the pair Examples:Pair<Integer> intPair = new Pair<>(17, 19);intPair.getFirst(); // returns 17intPair.getSecond(); // returns 19intPair.swap();intPair.getFirst(); // returns 19intPair.getSecond(); // returns 17Pair<String> strPair = new Pair<>("Erick", "Valdez");strPair.getFirst(); // returns "Erick"strPair.getSecond(); // returns "Valdez"strPair.swap();strPair.getFirst(); // returns "Valdez"strPair.getSecond(); // returns "Erick"     Pair.java /*** This class collects a pair of elements of different types.*/public class Pair<T, S> {private T first;private S second;/*** Constructs a pair containing two given elements.* * @param firstElement the first element* @param secondElement the second element*/public Pair(T firstElement, S secondElement) {first = firstElement;second = secondElement;}/*** Gets…

Java Code: For Lexer.java Make a HashMap of <String, TokenType> in your Lex class. Below is a list of the keywords that you need. Make token types and populate the hash map in your constructor (I would make a helper method that the constructor calls). while, if, do, for, break, continue, else, return, BEGIN, END, print, printf, next, in, delete, getline, exit, nextfile, function Modify “ProcessWord” so that it checks the hash map for known words and makes a token specific to the word with no value if the word is in the hash map, but WORD otherwise. For example, Input: for while hello do Output: FOR WHILE WORD(hello) DO Make a token type for string literals. In Lex, when you encounter a “, call a new method (I called it HandleStringLiteral() ) that reads up through the matching “ and creates a string literal token ( STRINGLITERAL(hello world) ). Be careful of two things: make sure that an empty string literal ( “” ) works and make sure to deal with escaped “ (String quote = “She…
