+** --- Day 1: Calorie Counting ---
+Santa's reindeer typically eat regular reindeer food, but they need a
+lot of [[/2018/day/25][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:
+
+#+begin_example
+1000
+2000
+3000
+
+4000
+
+5000
+6000
+
+7000
+8000
+9000
+
+10000
+#+end_example
+
+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?/
