Each distributed node holds several copies of the code. Its meaning?

Consider a open bucket hash table and closed bucket hash table in which the keys are student identifiers (strings of 6 digits). Assume the following number of buckets and hash function:   m = 100; hash(id) = first two digits of id #. Starting with an empty hash table, show the effect of successively adding the following student identifiers: 000014, 990021, 990019, 970036, 000015, 970012, 970023. Use following function as second hash function hash(id) = last digit of id # Show the effect of deleting 000014 from the hash table. (Java Programming DSA)

Bridge Self Learning Algorithm. Five LANs are connected by four bridges. Each bridge maintains two tables that describe what stations are in each LAN. Initially, all the tables are empty. Show how the tables of the four bridges change after each of the following events happen in sequence. A sends a frame to B B sends a frame to A C sends a frame to A G sends a frame to B

Given the code:  import java.util.HashMap; import java.util.LinkedList; import java.util.Scanner;   public class Controller { privateHashMap<String,LinkedList<Stock>>stockMap;   publicController(){ stockMap=newHashMap<>(); Scannerinput=newScanner(System.in);   do{ // Prompt for stock name or option to quit System.out.print("Enter stock name or 3 to quit: "); StringstockName=input.next(); if(stockName.equals("3")){ break;// Exit if user inputs '3' }   // Get or create a list for the specified stock LinkedList<Stock>stockList=stockMap.computeIfAbsent(stockName,k->newLinkedList<>());   // Prompt to buy or sell System.out.print("Input 1 to buy, 2 to sell: "); intcontrolNum=input.nextInt(); System.out.print("How many stocks: "); intquantity=input.nextInt();   if(controlNum==1){ // Buying stocks System.out.print("At what price: "); doubleprice=input.nextDouble(); buyStock(stockList,stockName,quantity,price); }else{ // Selling stocks System.out.print("Press…

The hash function h(k)= [(m(kA mod 1)] for A = 2-³ is used to insert the keys 61, 62, 63, 64, and 65 into a hash table of size m = 1000. The order of the hash codes in the table are given by a. 625, 125, 0, 750, 875 b. 625, 750, 625, 125, 0 c. 625,125, 0, 875, 750 d. 625, 750, 875, 0, 125 e. 625, 750, 125, 875, 0

Under indirect communication  process P wants to communicate with process Q using mailbox X.Which of the following primitives are  required. a. send (X,Message), receive(X,Message) b. send (P,Message), receive (X,Message) c. send (X,Message),receive(Q,Message)  d. send (P,Message), receive (Q,Message)

Java - Hash table valsTable uses quadratic probing, a hash function of key % 10, c1 = 1, and c2 = 1.

Vehicle routing problems concern the linking of a group of customers who must be visited to a set of vehicles and respective drivers, also involving the programming and sequencing of visits. In the method that is based on the concept of gain, the worst possible situation is assumed: the vehicle leaves the DC with the goods destined for a single customer and, after delivery, the vehicle returns to the DC. Then another customer is inserted in this route. This method is known under the name of:  ( ) Clark & ​​Wright ( )Insertion of the furthest point ( ) II - OPT ( ) scan ( )III - OPT

The data that makes up our hash map is all kept in a single LinkedList container due to the way the map was designed. This significantly reduces a hash map's efficiency.   The data that makes up our hash map is all kept in a single LinkedList container due to the way the map was designed.
