+# Day 10: Elves Look, Elves Say
+Today, the Elves are playing a game called [look-and-say](https://en.wikipedia.org/wiki/Look-and-say_sequence). 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` `1`s).
+
+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 `1`s).
+* `111221` becomes `312211` (three `1`s, two `2`s, and one `1`).
+
+Starting with the digits in your puzzle input, apply this process `40` times. What is **the length of the result**?
