+--- Day 4: Secure Container ---
+
+You arrive at the Venus fuel depot only to discover it's protected by a password.  The Elves had
+written the password on a sticky note, but someone threw it out.
+
+However, they do remember a few key facts about the password:
+
+
+ - It is a six-digit number.
+
+ - The value is within the range given in your puzzle input.
+
+ - Two adjacent digits are the same (like 22 in 122345).
+
+ - Going from left to right, the digits never decrease; they only ever increase or stay
+the same (like 111123 or 135679).
+
+
+Other than the range rule, the following are true:
+
+
+ - 111111 meets these criteria (double 11, never decreases).
+
+ - 223450 does not meet these criteria (decreasing pair of digits 50).
+
+ - 123789 does not meet these criteria (no double).
+
+
+How many different passwords within the range given in your puzzle input meet these
+criteria?
