--- Day 1: No Time for a Taxicab ---
|
||||
|
||||
Santa's sleigh uses a very high-precision clock to guide its movements, and the clock's oscillator is regulated
|
||||
by stars. Unfortunately, the stars have been stolen... by the Easter Bunny. To save Christmas, Santa needs you
|
||||
to retrieve all fifty stars by December 25th.
|
||||
|
||||
Collect stars by solving puzzles. Two puzzles will be made available on each day in the advent calendar; the
|
||||
second puzzle is unlocked when you complete the first. Each puzzle grants one star. Good luck!
|
||||
|
||||
You're airdropped near Easter Bunny Headquarters in a city somewhere. "Near", unfortunately, is as close as you
|
||||
can get - the instructions on the Easter Bunny Recruiting Document the Elves intercepted start here, and nobody
|
||||
had time to work them out further.
|
||||
|
||||
The Document indicates that you should start at the given coordinates (where you just landed) and face North.
|
||||
Then, follow the provided sequence: either turn left (L) or right (R) 90 degrees, then walk forward the given
|
||||
number of blocks, ending at a new intersection.
|
||||
|
||||
There's no time to follow such ridiculous instructions on foot, though, so you take a moment and work out the
|
||||
destination. Given that you can only walk on the street grid of the city, how far is the shortest path to the
|
||||
destination?
|
||||
|
||||
For example:
|
||||
|
||||
• Following R2, L3 leaves you 2 blocks East and 3 blocks North, or 5 blocks away.
|
||||
• R2, R2, R2 leaves you 2 blocks due South of your starting position, which is 2 blocks away.
|
||||
• R5, L5, R5, R3 leaves you 12 blocks away.
|
||||
|
||||
How many blocks away is Easter Bunny HQ?
|
||||
|
||||
