- Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C 2 D, E, and F 3 G, H, and I 4 J, K, and L 5 M, N, and O 6 P, Q, R, and S 7 T, U, and V 8 W, X, Y, and Z 9 Write a program that asks the user to enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD the application should display 555-438-3663. Gaddis Tony. Starting Out with Python (2-downloads) (p. 367). Pearson Education. Kindle Edition.For each expression in the left-hand column, indicate its value in the right-hand column. Be sure to list a constant of appropriate type (e.g., 7.0 rather than 7 for a double, Strings in "quotes").

- 20.15 LAB: Interstate highway numbers Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, I-405 services I-5, and I-290 services I-90. Note: 200 is not a valid auxiliary highway because 00 is not a valid primary highway number. Given a highway number, indicate whether it is primary, auxillary, and what direction(s) it travels.

Write a program to read the data from the file and produce the average temperature and average humidity for all the records in the file. This is a very large file - it is the actual temperature and humidity data from our server room. You would spend hours trying to do this manually, with a calculator, and you likely would make mistakes along the way. This is where computers are far superior to humans when dealing with boring, repetitive tasks.

- Currently in Brazil (year 2021), landline numbers are 8 digits long, and cell phone numbers, 9 digits. This number is regional, so to complete an identification of the user in Brazil that a number corresponds, it is also important the area code (DDD), composed of 2 digits. It's common people provide their phone number either including the area code, or not including it. Just following these size rules, some examples of phone numbers valid in Brazil: 2191231616511323161657191231616532323161632316165912316165 Make a function that receives as input a string containing a sequence of digits, which is supposed to it matches the phone number entered by a user (assume this string it only has digits). Your function must identify if the phone number is a valid number in Brazil (what means, if it fits one of the acceptable standards). If so, your function should return a tuple with two strings, the first containing exactly two digits that match the DDD (or empty string, if the area code was not…in the United States, telephone numbers consist of a three digit area code followed by a seven digit local number. Suppose neither the first digit of an area code nor the first digit of a local number can be a zero but that all other choices are acceptable. do not use commas when you write your number. For example enter 3356789 NOT 3,456,789Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999 and service the primary highway indicated by the rightmost two digits. Thus, the 405 services the 5, and the 290 services the 90. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also, indicate if the (primary) highway runs north/south or east/west. Ex: If the input is: 90 The output is: The 90 is primary, going east/west. Ex: If the input is: 290 The output is: The 290 is auxiliary, serving the 90, going east/west. Ex: If the input is: 0 Or any number not between 1 and 999, the output is: 0 is not a valid interstate highway number. import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int highwayNumber; int…
- In city street grids, intersections are often defined by two integers, counting the position of horizontal and vertical streets (sometimes called streets and avenues). Imagine traveling from position (h1, v1) to (h2, v2). How many blocks do you traverse?Write a program that prompts the user for the current US population, and the names and population of five major cities in different states. Your program will calculate the percentage of each city’s population based on total US population. The program will display a table with the state, city, population, and percentage. Finally, the program will print a message with the names and populations of the least and most populous cities.AlgorithmI need an answer without plagiarism and please type a paragraph about how did you solve your solution after you solved Also, code answer is not allowed
