+# Instructions
+
+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.
