1. Consider the following algorithm, which takes as input n EN: Initialize variables j = n and s = 0. While j > 0, do the following: Increment s by i Decrement j by 1 Output the value of s. Your task below is to prove (across several parts) that the above al- gorithm computes the sum of the first n positive integers. Use the following: A Pre-condition: ne N+ ján A s=0 Post-condition: s= i Loop invariant I: s= = {i=j+11 A MEN (Let me remind you of a convention regarding summation notation: If the lower limit is greater than the upper limit, then the sum is 0.) (a) (2 points) Prove that the pre-condition implies I. (b) (4 points) Prove that if I and the loop condition both hold right before an iteration of the loop, then I holds right after the itera- tion.

Write a program that displays a table of the Celsius temperatures 0 through 20 and their Fahrenheit equivalents. The formula for converting a temperature from Celsius to Fahrenheit is F = 9/5* C + 32 where F is the Fahrenheit temperature, and C is the Celsius temperature.

B.9 Programming Environments and Related Costs Programming environment: Python 3.9 along with Numpy, Pandas, Seaborn, matplotlib. pyplot, ipywidgets, and default Python libraries. A file converter to convert any common database file types into CSV files Statistics tracking software for tracking usage statistics during the first deployment There are no associated costs with the programming environment as all of these tools are available as no-cost open-source software. - Environment Costs: We will need workstations and storage hardware to facilitate the deployment phases. Our developers will need workstations that can connect to a central network to begin programming, testing, and collecting data analytics. We are budgeting $25,000 to the environment costs and these costs will be accounted for in the first installment payment Human Resource Requirements We require a staff of six developers to complete the project. They will each be paid a monthly salary of $5,000 per month. The estimate time of completion is two months so a total of $60,000 of the total budget should go towards employee salaries. Phase one (Deployable application): 120 development hours – total cost: $150,000 (this includes the equipment cost and the first month salary payments). Phase two (Major Feature Updates and Bug Fixes): 160 development hours + 1 week of allocated backlog - total cost: $350,000. The additional costs for this phase are incurred from the following: o More developer hours o Deployment costs associated with getting the product to customers o Hiring outside testers o Increased hardware requirements needed to scale the application o A reserve for unseen costs -

Magic Dates The date June 10, 1960 is special because when we write it in the following format, the month times the day equals the year: 6/10/60 Write a program that asks the user to enter a month (in numeric form), a day, and a two-digit year. The program should then determine whether the month times the day is equal to the year. If so, it should display a message saying the date is magic. Otherwise, it should display a a message saying the date is not magic. Sample run 1: Enter a month : 3 Enter a day : 5 Enter a year (YY): 10 You entered 3/5/10. This date is not magic. Sample run 2 Enter a month : 6 Enter a day Enter a year (YY): 60 . 10 O O You entered 6/10/60. This date is magic.

Write a program that compares the area of two rectangles. The program prompts the user for the height and width of both rectangles. You can assume the data type for height and width are int. The program will compare the area of both rectangles and use the if statement to decide if they have the same area, or one is larger than the other as described below: Both have the same area, it will print "Both rectangles have the same area." O First has larger area, it will print "The first rectangle has larger area.” Second has larger area, it will print "The second rectangle has larger area." This program compares area of rectangles. Enter height of rectangle 1: 5 Enter width of rectangle i : 2 Enter height of rectangle 2: 10 Enter width of rectangle 2 : 5 The second rectangle has larger area.
