# Day 24 Puzzle Text.
|
||||
|
||||
<article class="day-desc"><h2>--- Day 24: Blizzard Basin ---</h2><p>With everything replanted for next year (and with elephants and monkeys to tend the grove), you and the Elves leave for the extraction point.</p>
|
||||
<p>Partway up the mountain that shields the grove is a flat, open area that serves as the extraction point. It's a bit of a climb, but nothing the expedition can't handle.</p>
|
||||
<p>At least, that would normally be true; now that the mountain is covered in snow, things have become more difficult than the Elves are used to.</p>
|
||||
<p>As the expedition reaches a valley that must be traversed to reach the extraction site, you find that strong, turbulent winds are pushing small <em>blizzards</em> of snow and sharp ice around the valley. It's a good thing everyone packed warm clothes! To make it across safely, you'll need to find a way to avoid them.</p>
|
||||
<p>Fortunately, it's easy to see all of this from the entrance to the valley, so you make a map of the valley and the blizzards (your puzzle input). For example:</p>
|
||||
<pre><code>#.#####
|
||||
#.....#
|
||||
#>....#
|
||||
#.....#
|
||||
#...v.#
|
||||
#.....#
|
||||
#####.#
|
||||
</code></pre>
|
||||
<p>The walls of the valley are drawn as <code>#</code>; everything else is ground. Clear ground - where there is currently no blizzard - is drawn as <code>.</code>. Otherwise, blizzards are drawn with an arrow indicating their direction of motion: up (<code>^</code>), down (<code>v</code>), left (<code><</code>), or right (<code>></code>).</p>
|
||||
<p>The above map includes two blizzards, one moving right (<code>></code>) and one moving down (<code>v</code>). In one minute, each blizzard moves one position in the direction it is pointing:</p>
|
||||
<pre><code>#.#####
|
||||
#.....#
|
||||
#.>...#
|
||||
#.....#
|
||||
#.....#
|
||||
#...v.#
|
||||
#####.#
|
||||
</code></pre>
|
||||
<p>Due to <span title="I think, anyway. Do I look like a theoretical blizzacist?">conservation of blizzard energy</span>, as a blizzard reaches the wall of the valley, a new blizzard forms on the opposite side of the valley moving in the same direction. After another minute, the bottom downward-moving blizzard has been replaced with a new downward-moving blizzard at the top of the valley instead:</p>
|
||||
<pre><code>#.#####
|
||||
#...v.#
|
||||
#..>..#
|
||||
#.....#
|
||||
#.....#
|
||||
#.....#
|
||||
#####.#
|
||||
</code></pre>
|
||||
<p>Because blizzards are made of tiny snowflakes, they pass right through each other. After another minute, both blizzards temporarily occupy the same position, marked <code>2</code>:</p>
|
||||
<pre><code>#.#####
|
||||
#.....#
|
||||
#...2.#
|
||||
#.....#
|
||||
#.....#
|
||||
#.....#
|
||||
#####.#
|
||||
</code></pre>
|
||||
<p>After another minute, the situation resolves itself, giving each blizzard back its personal space:</p>
|
||||
<pre><code>#.#####
|
||||
#.....#
|
||||
#....>#
|
||||
#...v.#
|
||||
#.....#
|
||||
#.....#
|
||||
#####.#
|
||||
</code></pre>
|
||||
<p>Finally, after yet another minute, the rightward-facing blizzard on the right is replaced with a new one on the left facing the same direction:</p>
|
||||
<pre><code>#.#####
|
||||
#.....#
|
||||
#>....#
|
||||
#.....#
|
||||
#...v.#
|
||||
#.....#
|
||||
#####.#
|
||||
</code></pre>
|
||||
<p>This process repeats at least as long as you are observing it, but probably forever.</p>
|
||||
<p>Here is a more complex example:</p>
|
||||
<pre><code>#.######
|
||||
#>>.<^<#
|
||||
#.<..<<#
|
||||
#>v.><>#
|
||||
#<^v^^>#
|
||||
######.#
|
||||
</code></pre>
|
||||
<p>Your expedition begins in the only non-wall position in the top row and needs to reach the only non-wall position in the bottom row. On each minute, you can <em>move</em> up, down, left, or right, or you can <em>wait</em> in place. You and the blizzards act <em>simultaneously</em>, and you cannot share a position with a blizzard.</p>
|
||||
<p>In the above example, the fastest way to reach your goal requires <code><em>18</em></code> steps. Drawing the position of the expedition as <code>E</code>, one way to achieve this is:</p>
