+
+--- 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.
+
+   Both parts of this puzzle are complete! They provide two gold stars: **
