+# Day 5: Doesn't He Have Intern-Elves For This?
+Santa needs help figuring out which strings in his text file are naughty or nice.
+
+A **nice string** is one with all of the following properties:
+* It contains at least three vowels (`aeiou` only), like `aei`, `xazegov`, or `aeiouaeiouaeiou`.
+* It contains at least one letter that appears twice in a row, like `xx`, `abcdde` (`dd`), or `aabbccdd` (`aa`, `bb`, 
+`cc`, or `dd`).
+* It does **not** contain the strings `ab`, `cd`, `pq`, or `xy`, even if they are part of one of the other requirements.
+
+For example:
+* `ugknbfddgicrmopn` is nice because it has at least three vowels (`u...i...o...`), a double letter (`...dd...`), and 
+none of the disallowed substrings.
+* `aaa` is nice because it has at least three vowels and a double letter, even though the letters used by different 
+rules overlap.
+* `jchzalrnumimnmhp` is naughty because it has no double letter.
+* `haegwjzuvuyypxyu` is naughty because it contains the string `xy`.
+* `dvszwmarrgswjxmb` is naughty because it contains only one vowel.
+
+How many strings are nice?
