Sum Of Multiples
Given a number, find the sum of all the unique multiples of particular numbers up to but not including that number.
If we list all the natural numbers below 20 that are multiples of 3 or 5, we get 3, 5, 6, 9, 10, 12, 15, and 18.
The sum of these multiples is 78.
See this guide for instructions on how to setup your local R environment.
How to implement your solution
In each problem folder, there is a file named
<exercise_name>.R containing a function that returns a
NULL value. Place your implementation inside the body of the function.
How to run tests
Inside of RStudio, simply execute the
test_<exercise_name>.R script. This can be conveniently done with testthat's
auto_test function. Because exercism code and tests are in the same folder, use this same path for both
test_path parameters. On the command-line, you can also run
