Write this program using an IDE. Comment and style the code according to CS 200 Style Guide. Submit the source code files (.java) below. Make sure your source files are encoded in UTF-8. Some strange compiler errors are due to the text encoding not being correct. This lab asks you to create a text game Rock Paper Scissors. The rule of the game: There are two players in this game and they can choose Rock, Paper, or Scissors each time. Rock beats Scissors, Paper beats Rock and Scissors beat Paper. Your program needs to prompt a user to choose an action (Rock, Paper, or Scissors) and save their choice. The program randomly chooses an action (Hint: use .nextInt() to generate random integers in the range of [1,3]. 1 indicates Rock, 2 indicates Paper and 3 indicates Scissors.) Then the program determines who is the winner.
When input is R Please select one of [R/P/S]: You chose: Rock I chose: Scissors Rock beats scissors - you win! If the user enters the lowercase, your program can still recognize. When input is p Output should be Please select one of [R/P/S]: You chose: Paper I chose: Scissors Scissors beat paper - you lose! If the user enters invalid input, the program will give an error message and set the default choice as Rock When input is v Output should be Please select one of [R/P/S]: Invalid choice! Defaulting to Rock. I chose: Scissors Rock beats scissors - you win! If the user has the same result as the computer, your program should output: A Tie!

Explanation:

The program is well explained in the comments attache with each line of program. The program has three methods. One is the main method to start the game and prompts user to enter a choice and converts the user input choice to upper case. One is CompChoice method that generates three random numbers and uses switch statement to set 1 for Rock, 2 for Paper and 3 for Scissors . One method is results that takes computer choice and player choice as parameters to decide the winner. It uses if else statements to check if choice of user wins from choice of computer or vice versa. It uses a boolean variable youWin which is set to true when player choice beats computer choice otherwise is set to false. At the end if youWin is true then the player is declared winner otherwise not. The screenshot of the program output is attached.

You are given an array of integers, each with an unknown number of digits. You are also told the total number of digits of all the integers in the array is n. Provide an algorithm that will sort the array in O(n) time no matter how the digits are distributed among the elements in the array. (e.g. there might be one element with n digits, or n/2 elements with 2 digits, or the elements might be of all different lengths, etc. Be sure to justify in detail the run time of your algorithm.

Write a function called matches that takes two int arrays and their respective sizes, and returns the number of consecutive values that match between the two arrays starting at index 0. Suppose the two arrays are {3, 2, 5, 6, 1, 3} and {3, 2, 5, 2, 6, 1, 3} then the function should return 3 since the consecutive matches are for values 3, 2, and 5.

This assignment requires you to write a program to analyze a web page HTML file. Your program will read one character at a time from the file specifying the web page, count various attributes in the code for the page, and print a report to the console window giving information about the coding of the page.
Note that a search engine like Google uses at least one technique along similar lines. To calculate how popular (frequently visited or cited) a web page is, one technique is to look at as many other worldwide web pages as possible which are relevant, and count how many links the world's web pages contain back to the target page.
Learning Objectives
To utilize looping structures for the first time in a C++ program
To develop more sophisticated control structures using a combination of selection and looping
To read data from an input file
To gain more experience using manipulators to format output in C++
To consider examples of very simple hypertext markup language (HTML)
Use UNIX commands to obtain the text data files and be able to read from them
Problem Statement
Your program will analyze a few things about the way in which a web page is encoded. The program will ask the user for the name of a file containing a web page description. This input file must be stored in the correct folder with your program files, as discussed in class, and it must be encoded using hypertext markup language, or HTML. The analysis requires that you find the values of the following items for the page:
number of lines (every line ends with the EOLN marker; there will be an EOLN in front of the EOF)
number of tags (includes links and comments)
number of links
number of comments in the file
number of characters in the file (note that blanks and EOLNs do count)
number of characters inside tags
percentage of characters which occur inside tags, out of the total
Here is an example of a very simple HTML file:

Course Web Page
This course is about programming in C++.
Click here You may assume that the HTML files you must analyze use a very limited subset of basic HTML, which includes only the following "special" items: tag always starts with '<' and ends with > link always starts with " comment always starts with "" You may assume that a less-than symbol (<) ALWAYS indicates the start of a tag. A tag in HTML denotes an item that is not displayed on the web page, and often gives instructions to the web browser. For example, indicates that the next item is the overall title of the document, and indicates the end of that section. In tags, both upper and lowercase letters can be used. Note on links and comments: to identify a link, you may just look for an 'a' or 'A' which occurs just after a '<'. To identify a comment, you may just look for a '!' which follows just after a '' (that is, you do not have to check for the two hyphens). You may assume that these are the only HTML language elements you need to recognize, and that the HTML files you process contain absolutely no HTML syntax errors. Note: it is both good style because readability is increased, and convenient, to declare named constants for characters that are meaningful, for example const char TAG OPEN = ' Sample Input Files Program input is to be read from a text file. Your program must ask the user for interactive input of the file name. You can declare a variable to store the file name and read the user's response Miscellaneous Tips and Information You should not read the file more than once to perform the analysis. Reading the file more than once is very inefficient. The simplest, most reliable and consistent way to check for an end of file condition on a loop is by checking for the fail state, as shown in lectures. The eof function is not as reliable or consistent and is simply deemed "flaky" by many programmers as it can behave inconsistently for different input files and on different platforms. You may use only while loops on this project if you wish; you are not required to choose amongst while, do while and/or for loops until project 4 and all projects thereafter. Do not create any functions other than main() for this program. Do not use data structures such as arrays. You may only have ONE return statement and NO exit statements in your code. You may only use break statements inside a switch statement in the manner demonstrated in class; do not use break or continue statements inside loops. #include // used for interactive console I/O #include // used to format output #include // used to retrieve data from file #include // used to convert data to uppercase to simplify comparisons #include 11 for string class functions int main() { 1 //constants for analysing HTML attributes const char EOLN = '\n'; const char COMMENT_MARK = '!'; const char LINK='A'; //constants to format the output const int PAGEWIDTH = 70; const char UNDERLINE = '='; const char SPACE = const int PCT_WIDTH = 5; const int PCT_PRECISION = 2;

Consider the two lists A and B. List A is an anagram of list B if the following two conditions are true: 1.list A and list B have the same number of elements 2.each element of list A occurs the same number of times in list A and list BFor example, [3, 2, 4, 1, 2] and [2, 2, 3, 1, 4] are anagram of each other, but [2, 3, 1, 2] and [1, 3, 1, 2] are not.
