Problem 569. Encoding Google Maps Polylines
This problem is based on the Google Polyline Encoder algorithm. This is how Google Maps encodes a line for display on a map. You will be given a single latitude-longitude pair for which you must generate the encoded string used by the Google Maps API.
Example:
Given
lat = 42.3 lon = -71.35
then
str = '_vdaGnpnrL'
Here is the complete algorithm description. You can use this interactive tool to play around with it (I used it to generate the test points).

Ned,
I suggest creating a random lat and long test case. Use the bmtran entry#3 to solve for the correct vector. Once the test suite is updated it is possible to re-score.
