Implement a city database using ordered lists by using java. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using both: an arraybased list implementation, and a circular single linked list implementation.Use may the following node, SLL implementations to implement an ordered circular single linked list
Discrete distribution. Write a program DiscreteDistribution.java that takes an integer command-line argument m, followed by a sequence of positive integer command-line arguments a1,a2,…,ana1,a2,…,an, and prints m random indices (separated by whitespace), choosing each index i with probability proportional to ai. example: input = 25 1 1 1 1 1 1 output = 4135236543212345634523453
Implement a blog server in C 1. Implement get of all posts (GET /posts), and individual post (GET /post/1) 2. Implement creation of post (POST /posts). Allow the user to enter their name, but check that they are a valid user in db. Do error checking! The user should not specify the post id; that should come from the database. 3. Write three html files to test this; serve them with the blog server: index.html shows the list of posts with a link to each. post.html shows a post. publish.html allows the creation of a new post. Link these together as a user would expect!
implement a bridge simulation using threads and semaphores. The bridge (the grey rectangle)should have 600kg capacity. Each person (you can draw them as circles) should have a random weight between 40 and 140kg.The radius of the circle should be proportional to its weight.Their speed must be same with other persons.Create 100 person and test your program in Java.
Write a program to produce the first 100 Fibonacci numbers. A Fibonacci number is one that is the product of the prior two generated numbers. The sequence is seeded with the values of 0 and 1, so that the sequence starts off as 0 1 1 2 3 ... Fibonacci numbers are used in computing hash table locations for file management systems.
Write a python program that scans in a large number of tweets from a file, and prints the top 5 hashtags. Approach Parse each word in the file Find a way to isolate the hashtags from the rest of the tweet Compute the frequency of each unique hashtag. Find the top 5 hashtags. Caveats 1. Because this is public dataset, there are many tweets that use special characters that may cause issues during reading in your file. To avoid this, explicitly specify the encoding mode in open when reading in the file. with open('twitter_data.txt', 'r', encoding='utf8') as f: 2. When parsing hashtags be sure to change everything to lowercase. There are cases in the file where two hashtags are the same but differ in case. 3. There is no standard way of sorting a dictionary based on the values. Python gives you access to a sorted function where you can pass in a collection and also specify a comparator which outlines how you want to sort the values. This can be done with a one line lambda function.
Create an ErdosRenyi UF client that accepts an integer N from the command line, generates random pairs of integers between 0 and N-1, calls connected() to see if they are connected, union() if they are not (like in our development client), loops until all sites are connected, and prints the number of connections generated. Include your programme with a main() function that accepts N from the command line, calls count(), and prints the result, along with a static method count() that returns the total number of connections.
Create a Word doc (.docx) with Java . As a user, I want to create a Word document so that I can print a paper copy of a quiz. Generate a Word document that reflects a Canvas quiz. The creation of this Word document follows the method (if appropriate) that the Canvas quiz is generated. For example, pulling random questions from a test bank, assigning specific points to each question, randomizing multiple choice answer order, etc.
Create an object of MessageDigest class using the java.security.MessageDigest library. Initialize the object with your selection for an appropriate algorithm cipher. Use the digest() method of the class to generate a hash value of byte type from the unique data string (your first and last name). Convert the hash value to hex using the bytesToHex function. Create a RESTFul route using the @RequestMapping method to generate and return the required information, which includes the hash value, to the web browser. Here, is the code to edit package com.snhu.sslserver; import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController; @SpringBootApplicationpublic class ServerApplication { public static void main(String[] args) { SpringApplication.run(ServerApplication.class, args); } }…
You need to Cceate a responsive webpage that will display whether a SMS is spam or not.The user will only insert a SMS in a text field and he will be shown whether the text is spam or not.You need to code the spam detection software using Naive Bayes algorithm from scratch without using ANY libraries and you need to use PYTHON. Everytime i insert a SMS in the webpage the machine learning model should give more and more accurate result that the model should be the most accurate ever.
Consider the standard web log file in assets/logdata.txt. This file records the access a user makes when visiting a web page (like this one!). Each line of the log has the following items: • a host (e.g., '146.204.224.152') • a user_name (e.g., 'feest6811' note: sometimes the user name is missing! In this case, use '-' as the value for the username.) • the time a request was made (e.g., '21/Jun/2019:15:45:24 -0700') • the post request type (e.g., 'POST /incentivize HTTP/1.1' note: not everything is a POST!) Your task is to convert this into a list of dictionaries, where each dictionary looks like the following: example_dict = {"host": "146.204.224.152", "user_name": "feest6811", "time":"21/Jun/2019:15:45:24 -0700", "request": "POST /incentivize HTTP/1.1"} def logs (): with open("assets/logdata.txt", "r") as file: logdata = file.read() #YOUR CODE HERE raise NotImplementedError() one_item= {'host': '146.204.224.152', 'user name': 'feest6811', 'time': '21/Jun/2019:15:45:24 -0700',…
Need help with this code: You will write a client-server system for writing/storing notes. Each note has an ID (integer), a title (short text), and a body (long text). A client can have three kinds of requests to the server: upload a note, download a note (given its ID), and search for a note (given a keyword). In the case of search, the server will return a list of IDs and titles of notes whose titles contain the keyword. Design the database to store the notes. Design the Ul of the client. • Write code to implement the system. • You should use design patterns as in the Store Management System: 3-layer; Model-View-Controller; Singleton, Adapter. 1. StoreManager code public class StoreManager { private static StoreManager instance = null; private RemoteDataAdapter dao; private ProductView productView = null; public ProductView getProductView() { return productView; } private ProductController productController = null; public static StoreManager getlnstance() { if (instance == null)…
