Write a Perl program that uses a hash and a large number of operations on the hash. For example, the hash could store people's names and their ages. A random-number generator could be used to create three- character names and ages, which could be added to the hash. When a duplicate name was generated, it would cause an access to the hash but not add a new element. Rewrite the same program without using hashes. Compare the execution efficiency of the two. Compare the ease of programming and readability of the two.

- In class HashTable implement a hash table and consider the following:(i) Keys are integers (therefore also negative!) and should be stored in the tableint[] data.(ii) As a hash function take h(x) = (x · 701) mod 2000. The size of the table istherefore 2000. Be careful when computing the index of a negative key. Forexample, the index of the key x = −10 ish(−10) = (−7010) mod 2000 = (2000(−4) + 990) mod 2000 = 990.Hence, indices should be non-negative integers between 0 and 1999!(iii) Implement insert, which takes an integer and inserts it into a table.

Write a c++ program to add two large integers with up to 300 digits. One approach is to treat each number as array, each of whose elements is a block of digits of that number. For example, the integer 179,534,672,198 might be stored as block[0] =198, block[1] = 672, block[2] = 534, block[3] = 179. Add the two integers (lists), element by element, carrying from one element to the next when necessary. NOTE: You don’t have to use string input for the numbers. {Hint: when does the extraction stop extracting characters from the input buffer? How does the get function work? What character is always placed in the input stream when you press enter } The user will input the numbers using the following format: User input is in bold and underlined. Enter the number using this format(###,###,###) up to 300 digits: 179,534,672,198 Enter the number using this format(###,###,###) up to 300 digits: 564,325 Addition Result: 179,535,236,523 Enter the number using this format(###,###,###) up to 300…

Implement a city database using a BST to store the database records. 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. The BST should be organized by city name. Your database should allow records to be inserted, deleted by name or coordinate, and searched by name or coordinate. Another operation that should be supported is to print all records within a given distance of a specified point.Collect running-time statistics for each operation. Which operations can be implemented reasonably efficiently (i.e., in O(log n) time in the average case) using a BST? Can the database system be made more efficient by using one or more additional BSTs to organize the records by location?
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!

JAVA PROGRAMMING Arrays are useful to process lists. A top-level domain (TLD) name is the last part of an Internet domain name like .com in example.com. A core generic top-level domain (core gTLD) is a TLD that is either .com, .net, .org, or .info. A restricted top-level domain is a TLD that is either .biz, .name, or .pro. A second-level domain is a single name that precedes a TLD as in apple in apple.com. The following program repeatedly prompts for a domain name, and indicates whether that domain name consists of a second-level domain followed by a core gTLD. Valid core gTLD's are stored in an array. For this program, a valid domain name must contain only one period, such as apple.com, but not support.apple.com. The program ends when the user presses just the Enter key in response to a prompt. 1-Run the program and enter domain names to validate. 2-Extend the program to also recognize restricted TLDs using an array, and statements to validate against that array. The program should…
