For more context, please see the discussion in the forum, as well as the pull request that updated the exercise in the problem-specifications repository: - https://forum.exercism.org/t/new-project-making-practice-exercises-more-consistent-and-human-across-exercism/3943 - https://github.com/exercism/problem-specifications/pull/2249 --- .../sum-of-multiples/.docs/instructions.md | 29 ++++++++++++------- .../sum-of-multiples/.docs/introduction.md | 6 ++++ 2 files changed, 25 insertions(+), 10 deletions(-) create mode 100644 exercises/practice/sum-of-multiples/.docs/introduction.md diff --git a/exercises/practice/sum-of-multiples/.docs/instructions.md b/exercises/practice/sum-of-multiples/.docs/instructions.md index 7b7ec00..9c824bf 100644 --- a/exercises/practice/sum-of-multiples/.docs/instructions.md +++ b/exercises/practice/sum-of-multiples/.docs/instructions.md @@ -1,18 +1,27 @@ # Instructions -Given a list of factors and a limit, add up all the unique multiples of the factors that are less than the limit. -All inputs will be greater than or equal to zero. +Your task is to write the code that calculates the energy points that get awarded to players when they complete a level. -## Example +The points awarded depend on two things: -Suppose the limit is 20 and the list of factors is [3, 5]. -We need to find the sum of all unique multiples of 3 and 5 that are less than 20. +- The level (a number) that the player completed. +- The base value of each magical item collected by the player during that level. -Multiples of 3 less than 20: 3, 6, 9, 12, 15, 18 -Multiples of 5 less than 20: 5, 10, 15 +The energy points are awarded according to the following rules: -The unique multiples are: 3, 5, 6, 9, 10, 12, 15, 18 +1.
