+# Using only the official postal (2-letter) abbreviations for the 50
+# U.S. states, write a script to find the longest English word you can
+# spell? Here is the list of U.S. states abbreviations as per wikipedia
+# page. This challenge was proposed by team member Neil Bowers.
+# https://en.wikipedia.org/wiki/List_of_U.S._state_abbreviations
+#
+# For example,
+# Pennsylvania + Connecticut = PACT
+# Wisconsin + North Dakota = WIND
+# Maine + Alabama = MEAL
+# California + Louisiana + Massachusetts + Rhode Island = Calamari
