Finding a treasure hidden by pirates is really easy. Everything you need for this is a map. It is widely known that pirates draw maps by hand and describe the algorithm to find a place in the following way: "Stand near a lone palm tree, do 30 steps towards the forest, 15 towards the lake, ..."
A journey through such route is usually a great opportunity to see the scenery... However, nowadays nobody has time for that. That's why treasure seekers have asked you to write a program that would determine the exact location of a treasure using a given map.
The input consists of multiple instructions
<Direction> <Distance>, separated with commas (that are followed by one whitespace each).
Direction is one of the following:
N - North,
S - South,
E - East,
W - West,
NE - Northeast,
NW - Northwest,
SE - Southeast,
SW - Southwest.
Distance is an integer (1 to 1000).
The result is the coordinates where you end up after finishing the instructions, with three decimal places, separated with a comma and a whitespace. Start location has zero coordinates (0, 0).
The first coordinate is X (East means coordinates larger than zero, West means less than zero).
The second coordinate is Y (North means more than zero, South means less than zero).
N 3, E 1, N 1, E 3, S 2, W 1
NE 42, NW 42, SE 42, SW 42
