- This is the implementation of the Caesar cipher (Section5.3 in the textbook), which we discussed in class. Caesar cipher is a simple approach toencoding messages by shifting each letter in a message along the alphabet by aconstant amount.Your code will be similar to Listing 5.1, but you must use CircularArrayQueue.javainstead of the Java API queue. //5.1 import java.util.*;public class Codes { public static void main(String[] args) { int[] key = {5, 12, -3, 8, -9, 4, 10}; Integer keyValue; String encoded = "", decoded = ""; String message = "All programmer are playwrights and all "+"computers are lausy actors."; Queue<Integer> encodingQueue = new LinkedList<Integer>(); Queue<Integer> decodingQueue = new LinkedList<Integer>(); for (int scan=0; scan < key.length; scan++) { encodingQueue.add(key[scan]); decodingQueue.add(key[scan]); } for (int scan=0; scan < message.length();…Write a JAVA program for HTML is the language of web pages. Items start and end with tags. A table starts with <table> and ends with </table>. In a table, a row starts with <tr> and ends with </tr>. In a row, a column starts with <td> and ends with </td>. Given two integers for rows and columns, generate an appropriately sized html table. Place the character c in each table cell. If the input is 2 3, the output is: <table> <tr> <td> c </td> <td> c </td> <td> c </td> </tr> <tr> <td> c </td> <td> c </td> <td> c </td> </tr> </table>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.

To Determine the checksum: Add all the digits together Determine what needs to be added to make the total a multiple of 10 The bar code also always starts and ends with a large bar. This is used by the scanner to align the letter. Drexel's Zip Code is 19104 The check digit is 5. The sum of the digits is 1+9+1+0+4 = 15. To make 15 a multiple of 10, we need to add 5. The bar code will be |:::|||:|:::::||||::::|::|:|:|:| The majority of work in this problem is done by digit. It makes sense to store the zip code as a string, not as an integer.

- In Python, Solve the locker riddle which reads as follows:Imagine 100 lockers numbered 1 to 100 with 100 students lined up in front of those 100lockers:The first student opens every locker.The second student closes every 2nd locker.The 3rd student changes every 3rd locker; if it’s closed, she opens it; if it’s open, she closes it.The 4th student changes every fourth locker (e.g., 4th, 8th, etc.).The 5th student changes every 5th locker (e.g., 5th, 10th, etc.).That same pattern continues for all 100 students. Which lockers are left open after all 100 students have walked the rowof lockers?Implement a Python program that solves N-Queens problem that retrieves a natural number n as an input and show the solution on the screen (if it exists).
