--- Day 1: Calorie Counting ---
|
|||
|
|
|
|||
|
|
Santa's reindeer typically eat regular reindeer food, but they need a lot of magical energy to deliver presents on Christmas.
|
|||
|
|
For that, their favorite snack is a special type of star fruit that only grows deep in the jungle. The Elves have brought you
|
|||
|
|
on their annual expedition to the grove where the fruit grows.
|
|||
|
|
|
|||
|
|
To supply enough magical energy, the expedition needs to retrieve a minimum of fifty stars by December 25th. Although the
|
|||
|
|
Elves assure you that the grove has plenty of fruit, you decide to grab any fruit you see along the way, just in case.
|
|||
|
|
|
|||
|
|
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!
|
|||
|
|
|
|||
|
|
The jungle must be too overgrown and difficult to navigate in vehicles or access from the air; the Elves' expedition
|
|||
|
|
traditionally goes on foot. As your boats approach land, the Elves begin taking inventory of their supplies. One important
|
|||
|
|
consideration is food - in particular, the number of Calories each Elf is carrying (your puzzle input).
|
|||
|
|
|
|||
|
|
The Elves take turns writing down the number of Calories contained by the various meals, snacks, rations, etc. that they've
|
|||
|
|
brought with them, one item per line. Each Elf separates their own inventory from the previous Elf's inventory (if any) by a
|
|||
|
|
blank line.
|
|||
|
|
|
|||
|
|
For example, suppose the Elves finish writing their items' Calories and end up with the following list:
|
|||
|
|
|
|||
|
|
1000
|
|||
|
|
2000
|
|||
|
|
3000
|
|||
|
|
|
|||
|
|
4000
|
|||
|
|
|
|||
|
|
5000
|
|||
|
|
6000
|
|||
|
|
|
|||
|
|
7000
|
|||
|
|
8000
|
|||
|
|
9000
|
|||
|
|
|
|||
|
|
10000
|
|||
|
|
|
|||
|
|
This list represents the Calories of the food carried by five Elves:
|
|||
|
|
|
|||
|
|
• The first Elf is carrying food with 1000, 2000, and 3000 Calories, a total of 6000 Calories.
|
|||
|
|
• The second Elf is carrying one food item with 4000 Calories.
|
|||
|
|
• The third Elf is carrying food with 5000 and 6000 Calories, a total of 11000 Calories.
|
|||
|
|
• The fourth Elf is carrying food with 7000, 8000, and 9000 Calories, a total of 24000 Calories.
|
|||
|
|
• The fifth Elf is carrying one food item with 10000 Calories.
|
|||
|
|
|
|||
|
|
In case the Elves get hungry and need extra snacks, they need to know which Elf to ask: they'd like to know how many Calories
|
|||
|
|
are being carried by the Elf carrying the most Calories. In the example above, this is 24000 (carried by the fourth Elf).
|
|||
|
|
|
|||
|
|
Find the Elf carrying the most Calories. How many total Calories is that Elf carrying?
|
|||
|
|
|
|||
|
|
Your puzzle answer was 72070.
|
|||
|
|
|
|||
|
|
--- Part Two ---
|
|||
|
|
|
|||
|
|
By the time you calculate the answer to the Elves' question, they've already realized that the Elf carrying the most Calories
|
|||
|
|
of food might eventually run out of snacks.
|
|||
|
|
|
|||
|
|
To avoid this unacceptable situation, the Elves would instead like to know the total Calories carried by the top three Elves
|
|||
|
|
carrying the most Calories. That way, even if one of those Elves runs out of snacks, they still have two backups.
|
|||
|
|
|
|||
|
|
In the example above, the top three Elves are the fourth Elf (with 24000 Calories), then the third Elf (with 11000 Calories),
|
|||
|
|
then the fifth Elf (with 10000 Calories). The sum of the Calories carried by these three elves is 45000.
|
|||
|
|
|
|||
|
|
Find the top three Elves carrying the most Calories. How many Calories are those Elves carrying in total?
|
|||
|
|
|
|||
|
|
Your puzzle answer was 211805.

|||
