I am trying to write a function that would take two lists of increasing more
precise location, and return the most specific level of geography that they
share.
myhouse={"Earth", "North America", "USA", "Illinois", "Champaign County",
"Urbana"};
friendshouse={"Earth", "North America", "USA", "Minnesota", "Ramsey County",
"St. Paul"};
In this case, the function should output USA.
I could do this procedurally well enough. But I am really trying to get
comfortable with functional programming.
The above is just a more digestible version of what I am really trying to
do. I want to find the lowest level of taxonomy that two species share.
Ex:
aphid={"Insecta", "Dicondylia", "Pterygota", "Neoptera", "Paraneoptera",
"Hemiptera", "Sternorrhyncha", "Aphidiformes", "Aphidomorpha", "Aphidoidea",
"Aphididae", "Aphidinae", "Macrosiphini", "Acyrthosiphon"};
mosquito={"Insecta", "Dicondylia", "Pterygota", "Neoptera", "Endopterygota",
"Diptera", "Nematocera", "Culicimorpha", "Culicoidea"};
answer = Neoptera
Thank a 10^6,
Jason
