+\--- Day 25: Snowverload ---
+----------
+
+*Still* somehow without snow, you go to the last place you haven't checked: the center of Snow Island, directly below the waterfall.
+
+Here, someone has clearly been trying to fix the problem. Scattered everywhere are hundreds of weather machines, almanacs, communication modules, hoof prints, machine parts, mirrors, lenses, and so on.
+
+Somehow, everything has been *wired together* into a massive snow-producing apparatus, but nothing seems to be running. You check a tiny screen on one of the communication modules: `Error 2023`. It doesn't say what `Error 2023` means, but it *does* have the phone number for a support line printed on it.
+
+"Hi, you've reached Weather Machines And So On, Inc. How can I help you?" You explain the situation.
+
+"Error 2023, you say? Why, that's a power overload error, of course! It means you have too many components plugged in. Try unplugging some components and--" You explain that there are hundreds of components here and you're in a bit of a hurry.
+
+"Well, let's see how bad it is; do you see a *big red reset button* somewhere? It should be on its own module. If you push it, it probably won't fix anything, but it'll report how overloaded things are." After a minute or two, you find the reset button; it's so big that it takes two hands just to get enough leverage to push it. Its screen then displays:
+
+```
+SYSTEM OVERLOAD!
+
+Connected components would require
+power equal to at least 100 stars!
+
+```
+
+"Wait, *how* many components did you say are plugged in? With that much equipment, you could produce snow for an *entire*--" You disconnect the call.
+
+You have nowhere near that many stars - you need to find a way to disconnect at least half of the equipment here, but it's already Christmas! You only have time to disconnect *three wires*.
+
+Fortunately, someone left a wiring diagram (your puzzle input) that shows *how the components are connected*. For example:
+
+```
+jqt: rhn xhk nvd
+rsh: frs pzl lsr
+xhk: hfx
+cmg: qnr nvd lhk bvb
+rhn: xhk bvb hfx
+bvb: xhk hfx
+pzl: lsr hfx nvd
+qnr: nvd
+ntq: jqt hfx bvb xhk
+nvd: lhk
+lsr: lhk
+rzs: qnr cmg lsr rsh
+frs: qnr lhk lsr
+
+```
+
+Each line shows the *name of a component*, a colon, and then *a list of other components* to which that component is connected. Connections aren't directional; `abc: xyz` and `xyz: abc` both represent the same configuration. Each connection between two components is represented only once, so some components might only ever appear on the left or right side of a colon.
+
+In this example, if you disconnect the wire between `hfx`/`pzl`, the wire between `bvb`/`cmg`, and the wire between `nvd`/`jqt`, you will *divide the components into two separate, disconnected groups*:
+
+* `*9*` components: `cmg`, `frs`, `lhk`, `lsr`, `nvd`, `pzl`, `qnr`, `rsh`, and `rzs`.
+* `*6*` components: `bvb`, `hfx`, `jqt`, `ntq`, `rhn`, and `xhk`.
+
+Multiplying the sizes of these groups together produces `*54*`.
+
+Find the three wires you need to disconnect in order to divide the components into two separate groups. *What do you get if you multiply the sizes of these two groups together?*
+
+Your puzzle answer was `546804`.
+
+\--- Part Two ---
+----------
+
+You climb over weather machines, under giant springs, and narrowly avoid a pile of pipes as you find and disconnect the three wires.
+
+A moment after you disconnect the last wire, the big red reset button module makes a small ding noise:
+
+```
+System overload resolved!
+Power required is now 50 stars.
+
+```
+
+Out of the corner of your eye, you notice goggles and a loose-fitting hard hat peeking at you from behind an ultra crucible. You think you see a faint glow, but before you can investigate, you hear another small ding:
+
+```
+Power required is now 49 stars.
+
+Please supply the necessary stars and
+push the button to restart the system.
+
+```
+
+If you like, you can .
+
+Both parts of this puzzle are complete! They provide two gold stars: \*\*
