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. diff --git a/exercises/practice/allergies/.meta/config.json b/exercises/practice/allergies/.meta/config.json
