+--- Day 8: Memory Maneuver ---
+
+The sleigh is much easier to pull than you'd expect for something its weight. Unfortunately, neither
+you nor the Elves know which way the North Pole is from here.
+
+You check your wrist device for anything that might help. It seems to have some kind of navigation
+system! Activating the navigation system produces more bad news: "Failed to start navigation
+system. Could not read software license file."
+
+The navigation system's license file consists of a list of numbers (your puzzle input). The numbers
+define a data structure which, when processed, produces some kind of tree that can be used to
+calculate the license number.
+
+The tree is made up of nodes; a single, outermost node forms the tree's root, and it contains all
+other nodes in the tree (or contains nodes that contain nodes, and so on).
+
+Specifically, a node consists of:
+
+
+ - A header, which is always exactly two numbers:
+
+ - The quantity of child nodes.
+
+ - The quantity of metadata entries.
+
+
+ - Zero or more child nodes (as specified in the header).
+
+ - One or more metadata entries (as specified in the header).
+
+
+
+Each child node is itself a node that has its own header, child nodes, and metadata. For example:
+
+2 3 0 3 10 11 12 1 1 0 1 99 2 1 1 2
+A----------------------------------
+ B----------- C-----------
+ D-----
+
+In this example, each node of the tree is also marked with an underline starting with a letter for
+easier identification. In it, there are four nodes:
+
+
+ - A, which has 2 child nodes (B, C) and 3 metadata entries (1, 1, 2).
+
+ - B, which has 0 child nodes and 3 metadata entries (10, 11, 12).
+
+ - C, which has 1 child node (D) and 1 metadata entry (2).
+
+ - D, which has 0 child nodes and 1 metadata entry (99).
+
+
+The first check done on the license file is to simply add up all of the metadata entries. In this
+example, that sum is 1+1+2+10+11+12+2+99=138.
+
+What is the sum of all metadata entries?

+--- Part Two ---
+
+Now you're ready to decode the image. The image is rendered by stacking the layers and aligning the
+pixels with the same positions in each layer. The digits indicate the color of the corresponding
+pixel: 0 is black, 1 is white, and 2 is transparent.
+
+The layers are rendered with the first layer in front and the last layer in back. So, if a given
+position has a transparent pixel in the first and second layers, a black pixel in the third layer,
+and a white pixel in the fourth layer, the final image would have a black pixel at that position.
+
+For example, given an image 2 pixels wide and 2 pixels tall, the image data 0222112222120000
+corresponds to the following image layers:
+
+Layer 1: 02
+ 22
+
+Layer 2: 11
+ 22
+
+Layer 3: 22
+ 12
+
+Layer 4: 00
+ 00
+
+Then, the full image can be found by determining the top visible pixel in each position:
+
+
+ - The top-left pixel is black because the top layer is 0.
+
+ - The top-right pixel is white because the top layer is 2 (transparent), but the second layer is 1.
+
+ - The bottom-left pixel is white because the top two layers are 2, but the third layer is 1.
+
+ - The bottom-right pixel is black because the only visible pixel in that position is 0 (from layer
+4).
+
+
+So, the final image looks like this:
+
+01
+10
+
+What message is produced after decoding your image?
