Question
Add a validation function using Javascript that does the following 2 things:
- validates that password entered by the user and reentered password match. Note that minlength ensures it's a minimum of 8 of characters. Test thoroughly!!! Note that usually you would want to check that password meets some minimum requirements such as it includes both upper and lowercase letters and either a number or special character. In Javascript, we use regular expressions to do this. For this assignments, just make sure the password and reentered password match.
- validates that the username isn't already taken. Create an array of existing valid usernames. Include Harry, Elizabeth, and Shana.

The Tourtise and The Hair In this lab, we will be simulating the classic race of the tourtise and the hare. The race will take place on two paths of 70 tiles, which spans from left to right. The path will have two lanes, one for each animal. The path will be represented as an array of 70 characters, where each character will be the following: · A dash(i.e, “-“), which represents an empty tile. · An “h”, which represents the hare on the hare lane. · A “t”, which represents the tourtise on the tortise lane. All tiles will be “empty” (i.e. set to the dash) with the exception of the tiles that are occupied by the animals. As the animals move, the previous tile the animal was on will be set to empty, and the new tile will be changed to either “h” or “t”. Tile 70 will be the finishing tile, and the first animal to that tile will be declared the winner of the race. We will use randomization to determine how far each animal will move. Since this race will be…arrow_forward
- Select all the statements that are true about Python's unittest module and Django's test framework: a. Django's test framework builds on Python's unittest module b. Django's TestCase class is a sub-class of unittest.TestCase c. A collection of unit tests is called a "test suite" d. Unit tests are run using the same database that the programmer uses for the development server e. HTML assert methods (such as assertHTMLEqual) are already part of Python's unittest.TestCasearrow_forwardHere is step one in my python project In this step we'll be translating a single letter to Morse Code and a single Morse Code to a letter. The only input validation will be on the menu selection to handle the case where the user has entered something other than 0, 1 or 2. We'll import a module of our own (provided for you) and we'll use the dictionaries in that module to do the translation. 1. Download the morse module to your folder. 2. Create your step_1.py program and import morse --> morse.py Download morse.py 3. Create your menu driven interface using a while loop with the following menu: Morse Code Translator 0: Exit 1: Translate a word into Morse Code 2: Translate Morse Code to text. 4. Use an if-elif-else construct, with 'else' explaining to the user that the selection was invalid and that only 0, 1 and 2 are acceptable inputs. 5. If the user enters "0", exit the program. 6. If the user enters "1": Prompt the user for a letter with the input() command and…arrow_forwardAdd a new Java class to your project by right clicking on the src folder in the Project pane and select New > Java Class.Enter Hours as the name for this class, and IntelliJ will add it to the files in the src folder for your project. Remember tocopy and insert the standard heading for the main method as you did for Program 2.Write a program that prompts the user to enter a number of hours, and produces the equivalent number of days as a wholenumber along with the number of hours left over. Assume that a day has exactly 24 hours. The following example showsthe format to use for your output, where the input entered by the user is underlined.Enter the number of hours: 100100 hours is 4 days, plus 4 hours.Define Variables: The number of hours will be a whole number, and we would like to obtain results as whole numbers ofdays and hours, so use the int data type to declare the variables to hold the numbers of hours input, as well as the results(the number of days and number of hours left…arrow_forward
- In python. Include docstring. Please follow requirements as listed below. Thanks. You are given a puzzle consisting of a row of squares that contain nonnegative integers, with a zero in the rightmost square. Keep in mind that it's possible for other squares to contain a zero. You have a token that starts on the leftmost square. On each turn, the token can shift left or right a number of squares exactly equal to the value in its current square, but is not allowed to move off either end. For example, if the row of squares contains these values: [2, 4, 5, 3, 1, 3, 1, 4, 0], then on the first turn the only legal move is to shift right two squares, because the starting square contains a 2, and the token can't move off the left end. The goal is to get the token to the rightmost square (that contains zero). This row has a solution (more than one), but not all rows do. If we start with the row [1, 3, 2, 1, 3, 4, 0], then there is no way for the token to reach the rightmost square. Write a…arrow_forwardWrite a method that takes two string parameters, and tells whether the first is a substring of the second. You can't use framework methods that do this for you, such as indexOf(). In other words, you have to write the loops yourself. But, you can use the primitive methods such as charAt(). Also analyze the program's performance and state the big-O complexity of your method. Provide a screenshot of the code working.arrow_forwardI need help with my assignment in my Java programing class.

- With your askForYesNo method, how would you get the same result with only using one if/else if/else statement?? (IN JAVA PROGRAMMING) You also need to fix up your styling: All your method comments need to be in a block comment (/** comment */) and should include the parameters taken and values returned All your variables need to have a line comment (//comment) next to them explaining what they are going to be used for import java.util.Scanner; /** * 4.3CR User Input Functions * a functions to read a number within a range, and read more natural boolean values from the user * * @author MEHAKPREET KAUR * @version 04/08/2021 */ public class UserInput { // method to diplay askForInt public static int askForInt(Scanner in, String ask, int min, int max){ int value; //value entered by user System.out.print(ask + "(" + min + "-" + max + "): "); value = in.nextInt(); //loop check for invalid value while(value < min || value > max){…arrow_forwardI'm having trouble understanding how to input the values needed to use the def of getInch and getCm.arrow_forward
