Background to the problem: A nutritional app assists users in assessing their dietary habits. For the purpose of evaluation, the app asks the members to report how many fat grams and how many carbohydrate grams they consume per day. To help users manage their calorie budgets more effectively, the app calculates the total calories derived from fat and carbohydrates, rounded to the nearest calorie. The problem: The purpose of this question is to write a program that will perform these nutritional calculations. Specifically, you will produce an estimate of the total calories as follows: The number of calories resulting from the fat are calculated by multiplying the fat grams by 9. Similarly, the number of calories that result from the carbohydrates are calculated as the carbohydrates grams multiplied by 4. Your individual number is tied to the total calories so that there is some margin of error in the estimates. For example, if a member reported of fat and of carbohydrates on a day and the individual number is 1.01123 then: Question ii (hel i.Develop an initial decomposition of the problem using the chevron notation (> and >>) from the module materials. Include your decomposition in your solution document. ii.Building on your decomposition for part c.i., develop an algorithm for solving the problem. Include this algorithm in your solution document, and also write down your PI and the individual number that you have obtained via Steps 1–3 from your PI.
