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[edit]

This is example problem set. In this example we are learning about lists and conditionals.

The Problem[edit]

Please consult the image of a leaderboard below

You must design an algorithm which creates the total number of points. The algorithm accepts as input a comma delimited list:

USER ID, BADGES, CHALLENGES, VIDEOS, QUIZZES

For QUIZZES, the input is passed as a 2 dimensional list indicated the quiz number and the number of attempts. Please see below for two different examples of inputs:

1234, 3, 12, 13, [[1,1],[2,5],[3,1],[4,2]]

In the example above, user 1234 has 3 badges, 12 challenges, 13 videos and has the following quiz data:

  • for quiz 1, there was 1 attempt
  • for quiz 2, there was 5 attempts
  • for quiz 3, there was 1 attempt
  • for quiz 4 there were 2 attempts.

Your program should output the user ID and the number of points that user has earned. An example of out should look like:

1234, 340

How you will be assessed[edit]

Your solution will be graded using the following axis:


Scope

  • To what extent does your code implement the features required by our specification?
  • To what extent is there evidence of effort?

Correctness

  • To what extent did your code meet specifications?
  • To what extent did your code meet unit tests?
  • To what extent is your code free of bugs?

Design

  • To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
  • To what extent is your code eliminating repetition?
  • To what extent is your code using functions appropriately?

Style

  • To what extent is your code readable?
  • To what extent is your code commented?
  • To what extent are your variables well named?
  • To what extent do you adhere to style guide?
