|
||||
--- Day 6: Wait For It ---
|
||||
|
||||
The ferry quickly brings you across Island Island. After asking around,
|
||||
you discover that there is indeed normally a large pile of sand somewhere
|
||||
near here, but you don't see anything besides lots of water and the small
|
||||
island where the ferry has docked.
|
||||
|
||||
As you try to figure out what to do next, you notice a poster on a wall
|
||||
near the ferry dock. "Boat races! Open to the public! Grand prize is an
|
||||
all-expenses-paid trip to Desert Island!" That must be where the sand
|
||||
comes from! Best of all, the boat races are starting in just a few
|
||||
minutes.
|
||||
|
||||
You manage to sign up as a competitor in the boat races just in time. The
|
||||
organizer explains that it's not really a traditional race - instead, you
|
||||
will get a fixed amount of time during which your boat has to travel as
|
||||
far as it can, and you win if your boat goes the farthest.
|
||||
|
||||
As part of signing up, you get a sheet of paper (your puzzle input) that
|
||||
lists the time allowed for each race and also the best distance ever
|
||||
recorded in that race. To guarantee you win the grand prize, you need to
|
||||
make sure you go farther in each race than the current record holder.
|
||||
|
||||
The organizer brings you over to the area where the boat races are held.
|
||||
The boats are much smaller than you expected - they're actually toy boats,
|
||||
each with a big button on top. Holding down the button charges the boat,
|
||||
and releasing the button allows the boat to move. Boats move faster if
|
||||
their button was held longer, but time spent holding the button counts
|
||||
against the total race time. You can only hold the button at the start of
|
||||
the race, and boats don't move until the button is released.
|
||||
|
||||
For example:
|
||||
|
||||
Time: 7 15 30
|
||||
Distance: 9 40 200
|
||||
|
||||
This document describes three races:
|
||||
|
||||
• The first race lasts 7 milliseconds. The record distance in this race
|
||||
is 9 millimeters.
|
||||
• The second race lasts 15 milliseconds. The record distance in this
|
||||
race is 40 millimeters.
|
||||
• The third race lasts 30 milliseconds. The record distance in this race
|
||||
is 200 millimeters.
|
||||
|
||||
Your toy boat has a starting speed of zero millimeters per millisecond.
|
||||
For each whole millisecond you spend at the beginning of the race holding
|
||||
down the button, the boat's speed increases by one millimeter per
|
||||
millisecond.
|
||||
|
||||
So, because the first race lasts 7 milliseconds, you only have a few
|
||||
options:
|
||||
|
||||
• Don't hold the button at all (that is, hold it for 0 milliseconds) at
|
||||
the start of the race. The boat won't move; it will have traveled 0
|
||||
millimeters by the end of the race.
|
||||
• Hold the button for 1 millisecond at the start of the race. Then, the
|
||||
boat will travel at a speed of 1 millimeter per millisecond for 6
|
||||
milliseconds, reaching a total distance traveled of 6 millimeters.
|
||||
• Hold the button for 2 milliseconds, giving the boat a speed of 2
|
||||
millimeters per millisecond. It will then get 5 milliseconds to move,
|
||||
reaching a total distance of 10 millimeters.
|
||||
• Hold the button for 3 milliseconds. After its remaining 4 milliseconds
|
||||
of travel time, the boat will have gone 12 millimeters.
|
||||
• Hold the button for 4 milliseconds. After its remaining 3 milliseconds
|
||||
of travel time, the boat will have gone 12 millimeters.
|
||||
• Hold the button for 5 milliseconds, causing the boat to travel a total
|
||||
of 10 millimeters.
|
||||
• Hold the button for 6 milliseconds, causing the boat to travel a total
|
||||
of 6 millimeters.
|
||||
• Hold the button for 7 milliseconds. That's the entire duration of the
|
||||
race. You never let go of the button. The boat can't move until you
|
||||
let go of the button. Please make sure you let go of the button so the
|
||||
boat gets to move. 0 millimeters.
|
||||
|
||||
Since the current record for this race is 9 millimeters, there are
|
||||
actually 4 different ways you could win: you could hold the button for 2,
|
||||
3, 4, or 5 milliseconds at the start of the race.
|
||||
|
||||
In the second race, you could hold the button for at least 4 milliseconds
|
||||
and at most 11 milliseconds and beat the record, a total of 8 different
|
||||
ways to win.
|
||||
|
||||
In the third race, you could hold the button for at least 11 milliseconds
|
||||
and no more than 19 milliseconds and still beat the record, a total of 9
|
||||
ways you could win.
|
||||
|
||||
To see how much margin of error you have, determine the number of ways you
|
||||
can beat the record in each race; in this example, if you multiply these
|
||||
values together, you get 288 (4 * 8 * 9).
|
||||
|
||||
Determine the number of ways you could beat the record in each race. What
|
||||
do you get if you multiply these numbers together?
|
||||
|
||||
Your puzzle answer was 449820.
|
||||
|
||||
--- Part Two ---
|
||||
|
||||
As the race is about to start, you realize the piece of paper with race
|
||||
times and record distances you got earlier actually just has very bad
|
||||
[16]kerning. There's really only one race - ignore the spaces between the
|
||||
numbers on each line.
|
||||
|
||||
So, the example from before:
|
||||
|
||||
Time: 7 15 30
|
||||
Distance: 9 40 200
|
||||
|
||||
...now instead means this:
|
||||
|
||||
Time: 71530
|
||||
Distance: 940200
|
||||
|
||||
Now, you have to figure out how many ways there are to win this single
|
||||
race. In this example, the race lasts for 71530 milliseconds and the
|
||||
record distance you need to beat is 940200 millimeters. You could hold the
|
||||
button anywhere from 14 to 71516 milliseconds and beat the record, a total
|
||||
of 71503 ways!
|
||||
|
||||
How many ways can you beat the record in this one much longer race?
|
||||
|
||||
Your puzzle answer was 42250895.
|
||||
|
||||
Both parts of this puzzle are complete! They provide two gold stars: **
|
||||
|
||||
At this point, you should [17]return to your Advent calendar and try
|
||||
another puzzle.

||||

||||
