+--- Day 10: Elves Look, Elves Say ---
+
+   Today, the Elves are playing a game called look-and-say. They take turns making sequences by
+   reading aloud the previous sequence and using that reading as the next sequence. For example,
+   211 is read as "one two, two ones", which becomes 1221 (1 2, 2 1s).
+
+   Look-and-say sequences are generated iteratively, using the previous value as input for the
+   next step. For each step, take the previous value, and replace each run of digits (like 111)
+   with the number of digits (3) followed by the digit itself (1).
+
+   For example:
+
+     • 1 becomes 11 (1 copy of digit 1).
+     • 11 becomes 21 (2 copies of digit 1).
+     • 21 becomes 1211 (one 2 followed by one 1).
+     • 1211 becomes 111221 (one 1, one 2, and two 1s).
+     • 111221 becomes 312211 (three 1s, two 2s, and one 1).
+
+   Starting with the digits in your puzzle input, apply this process 40 times. What is the length
+   of the result?
+
+   Your puzzle answer was 360154.
+
+--- Part Two ---
+
+   Neat, right? You might also enjoy hearing John Conway talking about this sequence (that's
+   Conway of Conway's Game of Life fame).
+
+   Now, starting again with the digits in your puzzle input, apply this process 50 times. What is
+   the length of the new result?
+
+   Your puzzle answer was 5103798.
+
+   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.
+
+   Your puzzle input was 1113122113.
