+## \-\-- Day 8: Matchsticks \-\--
+
+Space on the sleigh is limited this year, and so Santa will be bringing
+his list as a digital copy. He needs to know how much space it will take
+up when stored.
+
+It is common in many programming languages to provide a way to
+escape
+special characters in strings. For example,
+[C](https://en.wikipedia.org/wiki/Escape_sequences_in_C),
+[JavaScript](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String),
+[Perl](http://perldoc.perl.org/perlop.html#Quote-and-Quote-like-Operators),
+[Python](https://docs.python.org/2.0/ref/strings.html), and even
+[PHP](http://php.net/manual/en/language.types.string.php#language.types.string.syntax.double)
+handle special characters in very similar ways.
+
+However, it is important to realize the difference between the number of
+characters *in the code representation of the string literal* and the
+number of characters *in the in-memory string itself*.
+
+For example:
+
+-   `""` is `2` characters of code (the two double quotes), but the
+    string contains zero characters.
+-   `"abc"` is `5` characters of code, but `3` characters in the string
+    data.
+-   `"aaa\"aaa"` is `10` characters of code, but the string itself
+    contains six \"a\" characters and a single, escaped quote character,
+    for a total of `7` characters in the string data.
+-   `"\x27"` is `6` characters of code, but the string itself contains
+    just one - an apostrophe (`'`), escaped using hexadecimal notation.
+
+Santa\'s list is a file that contains many double-quoted string
+literals, one on each line. The only escape sequences used are `\\`
+(which represents a single backslash), `\"` (which represents a lone
+double-quote character), and `\x` plus two hexadecimal characters (which
+represents a single character with that ASCII code).
+
+Disregarding the whitespace in the file, what is *the number of
+characters of code for string literals* minus *the number of characters
+in memory for the values of the strings* in total for the entire file?
+
+For example, given the four strings above, the total number of
+characters of string code (`2 + 5 + 10 + 6 = 23`) minus the total number
+of characters in memory for string values (`0 + 3 + 7 + 1 = 11`) is
+`23 - 11 = 12`.
