--- Day 1: Not Quite Lisp ---
|
||||
|
||||
Santa was hoping for a white Christmas, but his weather machine's "snow" function is powered by
|
||||
stars, and he's fresh out! To save Christmas, he needs you to collect fifty stars by December
|
||||
25th.
|
||||
|
||||
Collect stars by helping Santa solve 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!
|
||||
|
||||
Here's an easy puzzle to warm you up.
|
||||
|
||||
Santa is trying to deliver presents in a large apartment building, but he can't find the right
|
||||
floor - the directions he got are a little confusing. He starts on the ground floor (floor 0)
|
||||
and then follows the instructions one character at a time.
|
||||
|
||||
An opening parenthesis, (, means he should go up one floor, and a closing parenthesis, ), means
|
||||
he should go down one floor.
|
||||
|
||||
The apartment building is very tall, and the basement is very deep; he will never find the top
|
||||
or bottom floors.
|
||||
|
||||
For example:
|
||||
|
||||
• (()) and ()() both result in floor 0.
|
||||
• ((( and (()(()( both result in floor 3.
|
||||
• ))((((( also results in floor 3.
|
||||
• ()) and ))( both result in floor -1 (the first basement level).
|
||||
• ))) and )())()) both result in floor -3.
|
||||
|
||||
To what floor do the instructions take Santa?
|
||||
|
||||
Your puzzle answer was 138.
|
||||
|
||||
--- Part Two ---
|
||||
|
||||
Now, given the same instructions, find the position of the first character that causes him to
|
||||
enter the basement (floor -1). The first character in the instructions has position 1, the
|
||||
second character has position 2, and so on.
|
||||
|
||||
For example:
|
||||
|
||||
• ) causes him to enter the basement at character position 1.
|
||||
• ()()) causes him to enter the basement at character position 5.
|
||||
|
||||
What is the position of the character that causes Santa to first enter the basement?
|
||||
|
||||
Your puzzle answer was 1771.
|
||||
|
||||
Both parts of this puzzle are complete! They provide two gold stars: **
|
||||
|
||||
At this point, you should return to your advent calendar and try another puzzle.
|
||||

||||
