Given a person's allergy score, determine whether or not they're allergic to a given item, and their full list of allergies.
An allergy test produces a single numeric score which contains the information about all the allergies the person has (that they were tested for).
The list of items (and their value) that were tested are:
- eggs (1)
- peanuts (2)
- shellfish (4)
- strawberries (8)
- tomatoes (16)
- chocolate (32)
- pollen (64)
- cats (128)
So if Tom is allergic to peanuts and chocolate, he gets a score of 34.
Now, given just that score of 34, your program should be able to say:
- Whether Tom is allergic to any one of those allergens listed above.
- All the allergens Tom is allergic to.
Note: a given score may include allergens not listed above (i.e. allergens that score 256, 512, 1024, etc.). Your program should ignore those components of the score. For example, if the allergy score is 257, your program should only report the eggs (1) allergy.
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.
In order to run the test, you can run the test file from the exercise
directory. For example, if the test suite is called
hello_world_test.rb, you can run the following command:
ruby hello_world_test.rb
To include color from the command line:
ruby -r minitest/pride hello_world_test.rb
