This a problem set for you to work through [1]

This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:

  1. to build your skill applying computational thinking to a problem
  2. to assess your knowledge and skills of different programming practices


What is this problem set trying to do

This problem set is helping you learn pseudocode.

The Problem

Given a collection with 10 numbers write a pseudocode algorithm to add them together and output an answer. You may only use methods available to a collection.

Those methods are:

  • addItem()
  • getNext()
  • resetNext()
  • hasNext()
  • isEmpty()

Please carefully studyDevote time and attention to gaining knowledge of (an academic subject), especially by means of books page four in this pseudo guide.

numbers_to_add = [12,13,14,15,16,17,18,19,20,21]

# Your pseudocode here. 

print("The answer is: ", answer")


Unit Tests

  • Input: A collection named "numbers_to_add
  • Expected output: "The answer is: 165"

Hacker Version

In addition to adding the numbers, average them. In this case, your output will be 16.5. Please remember, you can only use methods available to a collection.


How you will be assessed

Your solution will be graded using the following axis:


Scope

  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. does your code implement the features required by our specification?
  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. is there evidence of effort?

Correctness

  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. did your code meet specifications?
  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. did your code meet unit tests?
  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. is your code free of bugs?

DesignProduce a plan, simulation or model.

  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. is your code eliminating repetition?
  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. is your code using functions appropriately?

Style

  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. is your code readable?
  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. is your code commented?
  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. are your variables well named?
  • To what extentConsider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. do you adhere to style guide?
