Holy digits Batman! The Riddler is planning his next caper somewhere on Pennsylvania Avenue. In his usual sporting fashion, he has left the address in the form of a puzzle. The address on Pennsylvania is a four-digit number where:
■ All four digits are different
■ The digit in the thousands place is three times the digit in the tens place
■ The number is odd
■ The sum of the digits is 27

- (Computation) A magic square is a square of numbers with N rows and N columns, in which each integer value from 1 to (N * N) appears exactly once, and the sum of each column, each row, and each diagonal is the same value. For example, Figure 7.21 shows a magic square in which N=3, and the sum of the rows, columns, and diagonals is 15. Write a program that constructs and displays a magic square for a given odd number N. This is the algorithm:arrow_forwardJAVA LANGUAGE PLS THANK YOU 3. Negative Allergy by CodeChum Admin Whole numbers are great, but I think we should also pay attention to decimal numbers, too. So, how about we make a program that involves a lot of decimals? Instructions: Continuously ask for floating point values (decimal numbers) using the do…while() loop, sum them all up, and store the total into one variable. The loop shall only terminate for the following reasons: A negative decimal number is inputted (but still included in the total sum) The total sum reaches 100.0 or more Instructions Continuously ask for floating point values (decimal numbers) using the do…while() loop, sum them all up, and store the total into one variable.

- Python In this exercise, you will create a program that reads words from the user until the user enters a blank line. After the user enters a blank line your program should display each word entered by the user exactly once. The words should be displayed in the same order that they were entered (they don't have to be sorted by their meaning). For example, if the user enters: firstsecondfirstthirdsecond then your program should display: firstsecondthirdarrow_forwardChapter 5B Exercise 1 - Extra Exercise - Holy Digits Holy digits Batman! The Riddler is planning his next caper somewhere on Pennsylvania Avenue. In his usual sporting fashion, he has left the address in the form of a puzzle. The address on Pennsylvania is a four-digit number where: All four digits are different The digit in the thousands place is three times the digit in the tens place The number is odd The sum of the digits is 27 Write a program that uses a loop (or loops) to find the address where the Riddler plans to strike.arrow_forwardUSING FOR LOOP1.

- Write a complete program to generate a username based on a user's first and last name. Part One: Get a Valid First and Last Name ask the user for and read in their first and last name use a loop to validate the first name: it must be at least one character long and it must start with a letter use a loop to validate the last name: it must not contain any spaces Hint: use a nested loop. The outer loop will iterate until there is valid input. The inner loop will check each character in the String to see if any of them are whitespace. Part Two: Generate a Username generate a two-digit random number (i.e., a random number between 10 and 99, inclusive) create a username that is the following data concatenated: the first letter of their first name in lower case the first five characters of their last name in lower case; if the name is shorter than five characters, use the whole last name the two-digit number output the username to the user Additional Coding Requirements code…arrow_forwardOn Thursday, November 4, 2021, Big Man Games wrote: Computer programs are great at computing mathematical formulas. Once the formula is properly encoded you can use the code as much as you want without reprogramming it and you can share it with non-programmers without any trouble. This lab is an example of such a formula. Once you program it you won’t have to worry about the area of a circle again. Write and test a program that computes the area of a circle. This program should request a number representing a radius as input from the user. Use the formula 3.14 × radius2 to compute the area. Tip: There are a couple of ways to code an exponent. Look in the Operators unit for help (and you can’t use an x for multiplication). Tip: You will need to use the float data type to compute the remainder. The output should explain the results. Don’t just print a number. Tip: For your print statement you will need to use the comma, “,”, or plus, “+” symbols to stitch your output together.

The equation below is what is used to solve for . Remember, there will be two solutions for x (not necessarily distinct). No loops are necessary, so don’t include any. To find the two solutions for this equation, you will use the quadratic formula: Remember that it must be solved for both the and : You will ask the user to input a value for A, B, and C (in that order, using those same letters), then you will use those values to find the two values of x as above. Your output MUST then display the original quadratic equation back to the user with their coefficients in place, and then output the two results. We will assume that the user will not put zero for A. *Format ALL OUTPUT VALUES (including the equation) to have only two decimal places. There is a test case below.

- LAB: Loops: Output range with increment of 10 Write a program that reads two integers as input, and outputs the first integer and subsequent increments of 10 as long as the value is less than or equal to the second integer. Ex: If the input is: -15 30 the output is: -15 -5 5 15 25 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last.arrow_forwardThe Lottery Problem: • The lottery draws a number that is the winning number • The number should be between 0 and 999 • Have someone play • The person tells how many tickets they want • The person always does “quick pick” (let the computer pick the number for them) and gets one number between 0 and 999 for each ticket bought • The program reports how many tickets win of the ones bought • NOTE: A ticket “wins” if it matches the winning number previously chosen • Write working code with at least one function and one sub other than “main”arrow_forwardpython The intent of this program is to manage a set of contacts. Each contact will have data associated with it: Id – number/integer First Name – string Last Name – string Age – number/integer Phone Number – string Email – string Anything else you’d like to add to make yours unique (can result in extra credit) Gender – character or string (m/f/o) Twitter ID, Facebook Id, etc You must allow the customer to do the following actions on the contact list: List all contacts Add contact Delete contact Edit contact Exit program You should leverage a database (PostgreSQL) to save everything to the DB and read from it. You should use classes for this assignment. This means you should have two classes: Contact – all the attributes/properties described above with appropriate constructor.
