Series
Given a string of digits, output all the contiguous substrings of length n in
that string.
For example, the string "49142" has the following 3-digit series:
- 491
- 914
- 142
And the following 4-digit series:
- 4914
- 9142
And if you ask for a 6-digit series from a 5-digit string, you deserve whatever you get.
Note that these series are only required to occupy adjacent positions in the input; the digits need not be numerically consecutive.
For installation and learning resources, refer to the exercism help page.
For running the tests provided, you will need the Minitest gem. Open a terminal window and run the following command to install minitest:
gem install minitest
If you would like color output, you can require 'minitest/pride' in
the test file, or note the alternative instruction, below, for running
the test file.
Run the tests from the exercise directory using the following command:
ruby series_test.rb
To include color from the command line:
ruby -r minitest/pride series_test.rb
