+--- Day 11: Corporate Policy ---
+
+   Santa's previous password expired, and he needs help choosing a new one.
+
+   To help him remember his new password after the old one expires, Santa has devised a method of
+   coming up with a password based on the previous one. Corporate policy dictates that passwords
+   must be exactly eight lowercase letters (for security reasons), so he finds his new password by
+   incrementing his old password string repeatedly until it is valid.
+
+   Incrementing is just like counting with numbers: xx, xy, xz, ya, yb, and so on. Increase the
+   rightmost letter one step; if it was z, it wraps around to a, and repeat with the next letter
+   to the left until one doesn't wrap around.
+
+   Unfortunately for Santa, a new Security-Elf recently started, and he has imposed some
+   additional password requirements:
+
+     • Passwords must include one increasing straight of at least three letters, like abc, bcd,
+       cde, and so on, up to xyz. They cannot skip letters; abd doesn't count.
+     • Passwords may not contain the letters i, o, or l, as these letters can be mistaken for
+       other characters and are therefore confusing.
+     • Passwords must contain at least two different, non-overlapping pairs of letters, like aa,
+       bb, or zz.
+
+   For example:
+
+     • hijklmmn meets the first requirement (because it contains the straight hij) but fails the
+       second requirement requirement (because it contains i and l).
+     • abbceffg meets the third requirement (because it repeats bb and ff) but fails the first
+       requirement.
+     • abbcegjk fails the third requirement, because it only has one double letter (bb).
+     • The next password after abcdefgh is abcdffaa.
+     • The next password after ghijklmn is ghjaabcc, because you eventually skip all the passwords
+       that start with ghi..., since i is not allowed.
+
+   Given Santa's current password (your puzzle input), what should his next password be?
+
+   Your puzzle answer was hepxxyzz.
+
+--- Part Two ---
+
+   Santa's password expired again. What's the next one?
+
+   Your puzzle answer was heqaabcc.
+
+   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 hepxcrrq.
