+--- Day 17: Clumsy Crucible ---
+
+   The lava starts flowing rapidly once the Lava Production Facility is
+   operational. As you leave, the reindeer offers you a parachute, allowing
+   you to quickly reach Gear Island.
+
+   As you descend, your bird's-eye view of Gear Island reveals why you had
+   trouble finding anyone on your way up: half of Gear Island is empty, but
+   the half below you is a giant factory city!
+
+   You land near the gradually-filling pool of lava at the base of your new
+   lavafall. Lavaducts will eventually carry the lava throughout the city,
+   but to make use of it immediately, Elves are loading it into large
+   [16]crucibles on wheels.
+
+   The crucibles are top-heavy and pushed by hand. Unfortunately, the
+   crucibles become very difficult to steer at high speeds, and so it can be
+   hard to go in a straight line for very long.
+
+   To get Desert Island the machine parts it needs as soon as possible,
+   you'll need to find the best way to get the crucible from the lava pool to
+   the machine parts factory. To do this, you need to minimize heat loss
+   while choosing a route that doesn't require the crucible to go in a
+   straight line for too long.
+
+   Fortunately, the Elves here have a map (your puzzle input) that uses
+   traffic patterns, ambient temperature, and hundreds of other parameters to
+   calculate exactly how much heat loss can be expected for a crucible
+   entering any particular city block.
+
+   For example:
+
+ 2413432311323
+ 3215453535623
+ 3255245654254
+ 3446585845452
+ 4546657867536
+ 1438598798454
+ 4457876987766
+ 3637877979653
+ 4654967986887
+ 4564679986453
+ 1224686865563
+ 2546548887735
+ 4322674655533
+
+   Each city block is marked by a single digit that represents the amount of
+   heat loss if the crucible enters that block. The starting point, the lava
+   pool, is the top-left city block; the destination, the machine parts
+   factory, is the bottom-right city block. (Because you already start in the
+   top-left block, you don't incur that block's heat loss unless you leave
+   that block and then return to it.)
+
+   Because it is difficult to keep the top-heavy crucible going in a straight
+   line for very long, it can move at most three blocks in a single direction
+   before it must turn 90 degrees left or right. The crucible also can't
+   reverse direction; after entering each city block, it may only turn left,
+   continue straight, or turn right.
+
+   One way to minimize heat loss is this path:
+
+ 2>>34^>>>1323
+ 32v>>>35v5623
+ 32552456v>>54
+ 3446585845v52
+ 4546657867v>6
+ 14385987984v4
+ 44578769877v6
+ 36378779796v>
+ 465496798688v
+ 456467998645v
+ 12246868655<v
+ 25465488877v5
+ 43226746555v>
+
+   This path never moves more than three consecutive blocks in the same
+   direction and incurs a heat loss of only 102.
+
+   Directing the crucible from the lava pool to the machine parts factory,
+   but not moving more than three consecutive blocks in the same direction,
+   what is the least heat loss it can incur?
+
+   Your puzzle answer was 1001.
+
+--- Part Two ---
+
+   The crucibles of lava simply aren't large enough to provide an adequate
+   supply of lava to the machine parts factory. Instead, the Elves are going
+   to upgrade to ultra crucibles.
+
+   Ultra crucibles are even more difficult to steer than normal crucibles.
+   Not only do they have trouble going in a straight line, but they also have
+   trouble turning!
+
+   Once an ultra crucible starts moving in a direction, it needs to move a
+   minimum of four blocks in that direction before it can turn (or even
+   before it can stop at the end). However, it will eventually start to get
+   wobbly: an ultra crucible can move a maximum of ten consecutive blocks
+   without turning.
+
+   In the above example, an ultra crucible could follow this path to minimize
+   heat loss:
+
+ 2>>>>>>>>1323
+ 32154535v5623
+ 32552456v4254
+ 34465858v5452
+ 45466578v>>>>
+ 143859879845v
+ 445787698776v
+ 363787797965v
+ 465496798688v
+ 456467998645v
+ 122468686556v
+ 254654888773v
+ 432267465553v
+
+   In the above example, an ultra crucible would incur the minimum possible
+   heat loss of 94.
+
+   Here's another example:
+
+ 111111111111
+ 999999999991
+ 999999999991
+ 999999999991
+ 999999999991
+
+   Sadly, an ultra crucible would need to take an unfortunate path like this
+   one:
+
+ 1>>>>>>>1111
+ 9999999v9991
+ 9999999v9991
+ 9999999v9991
+ 9999999v>>>>
+
+   This route causes the ultra crucible to incur the minimum possible heat
+   loss of 71.
+
+   Directing the ultra crucible from the lava pool to the machine parts
+   factory, what is the least heat loss it can incur?
+
+   Your puzzle answer was 1197.
