+--- Day 2: Red-Nosed Reports ---
+
+Fortunately, the first location The Historians want to search isn't a long walk from the Chief Historian's office.
+
+While the Red-Nosed Reindeer nuclear fusion/fission plant appears to contain no sign of the Chief Historian, the
+engineers there run up to you as soon as they see you. Apparently, they still talk about the time Rudolph was saved
+through molecular synthesis from a single electron.
+
+They're quick to add that - since you're already here - they'd really appreciate your help analyzing some unusual data
+from the Red-Nosed reactor. You turn to check if The Historians are waiting for you, but they seem to have already
+divided into groups that are currently searching every corner of the facility. You offer to help with the unusual data.
+
+The unusual data (your puzzle input) consists of many reports, one report per line. Each report is a list of numbers
+called levels that are separated by spaces. For example:
+
+7 6 4 2 1
+1 2 7 8 9
+9 7 6 2 1
+1 3 2 4 5
+8 6 4 4 1
+1 3 6 7 9
+
+This example data contains six reports each containing five levels.
+
+The engineers are trying to figure out which reports are safe. The Red-Nosed reactor safety systems can only
+tolerate levels that are either gradually increasing or gradually decreasing. So, a report only counts as safe if
+both of the following are true:
+
+    The levels are either all increasing or all decreasing.
+    Any two adjacent levels differ by at least one and at most three.
+
+In the example above, the reports can be found safe or unsafe by checking those rules:
+
+    7 6 4 2 1: Safe because the levels are all decreasing by 1 or 2.
+    1 2 7 8 9: Unsafe because 2 7 is an increase of 5.
+    9 7 6 2 1: Unsafe because 6 2 is a decrease of 4.
+    1 3 2 4 5: Unsafe because 1 3 is increasing but 3 2 is decreasing.
+    8 6 4 4 1: Unsafe because 4 4 is neither an increase or a decrease.
+    1 3 6 7 9: Safe because the levels are all increasing by 1, 2, or 3.
+
+So, in this example, 2 reports are safe.
+
+Analyze the unusual data from the engineers. How many reports are safe?
