- PROGRAMMING PROBLEM The inventory of a shoe store lists shoes by stock number. With each stock number, there is associated a style number in the range of 0 to 50, the number of pairs in each size (sizes range from 3 to 14) and a price. A program is to be written to keep track of the inventory. The user is given the following choices: enter a new record, display a record, change the price of the stock item, or change the number on hand. When specifying a record the user may give either the stock number, or the style number. The array index can be used as a stock number. If the user decides to change the stock on hand, the program should ask which sizes will have their stock on hand changed. The program should be designed to run indefinitely, keeping track of changed in stock.arrow_forwardAssignment 5C: Level Map Creator. There are a variety of ways that game developers store their level layouts. One simple method is to associate level elements with certain symbols, and then storing them in a 2D grid inside a text file. We will use our knowledge of 2D arrays to create a very simple Level Map Creator tool. The program should prompt the user to enter a width and height for the level. Then it should initialize a 2D array and fill every element with the *" symbol. Afterwards, the user should be given the following options via a menu: 1. Clear Level 2.

- Geometric Progression Printer As you might recall, a Geometric Progression (or GP) is a sequence of elements in which the next number in the sequence is obtained by multiplying the previous number by the common ratio. The next number in the sequence is obtained by using this formula: a_na_1* r(n-1) While the sum of all numbers in the sequence is obtained using any of these formulae: If r 1, sum = a* n If r != 1 and r> 1, sum= a[(r¹-1)/(r - 1)] If r != 1 and r < 1, sum = a[(1 - r¹)/(1-r)] where a n = next number in the sequence, a_1 = first number in the sequence, r = common ratio, n = number of terms Your task is to write a Python program that 1. Accepts the necessary inputs from the user, i.e., start value (a_1), common ratio (r), and number of generate to generate (n). 2.

Monthly payments are 5% of the listed purchase price, minus the down payment. Write a program that takes the purchase price as input. The program should display a table, with appropriate headers, of a payment schedule for the lifetime of the loan. Each row of the table should contain the following items: The month number (beginning with 1) The current total balance owed The interest owed for that month The amount of principal owed for that month The payment for that month The balance remaining after payment The amount of interest for a month is equal to balance × rate / 12. The amount of principal for a month is equal to the monthly payment minus the interest owed. An example of the program input and output is shown below: Enter the puchase price: 200 (SEE IMAGE FOR PURCHASE PRICE CHART) Results you should get: Input: 200 Output: Purchase price: 200…arrow_forward
- Manhattan skyline def manhattan_skyline(towers):This classic problem in computational geometry (essentially, geometry that can be done using only integer arithmetic; yes, that is an actual thing) is best illustrated by pictures and animations such as those on the page "The Skyline problem", so you can first check that it out to get an idea of what is going on. Given a list of rectangular towers as tuples (s, e, h) where s and e are the start and end x-coordinates (satisfying e>s) and h is the height of that tower, compute and return the total visible area of the towers, being careful not to double count two or more towers that are partially overlapping. All towers share the same flat ground baseline at the height. The classic solution illustrates the important sweep line technique that starts by creating a list of precisely those x-coordinate values where something relevant to the problem takes place. In this problem, the relevant x-coordinates are those where some tower either…arrow_forwardChrome Capture 767x397 Create a python program called code.py. Write a function named pi_multiples() that takes an integer parameter num. This function repeatedly asks the user to enter an integer between 2 and 50. Assume the user will always enter an integer, but if the number is outside this range, the loop must end. So, for any integer x entered within the range, your function must do the following; if x is divisible by num (the parameter), it must multiply x by the value of pi (call it result) and maintain a sum of these results. In every iteration of the loop your function must print x and the result. And when the loop terminates your function should return the sum. To test your function, call pi_multiples() function using any integer number of your choice (for num) and print the returned value. Hint: to use the pi value do the following import math and use math.pi for the value of pi. frames: 0 0/ 10 secs Zip your file, name it code.zip, and submit it using the link available in…arrow_forwardYou will write a program that allows the user to enter 10 songs and their artists into a playlist and will sort the entries by artist order.
