+# 2022 Day 05: Supply Stacks

+
+## Part 1
+
+The expedition can depart as soon as the final supplies have been unloaded from the ships. Supplies are stored in stacks of marked **crates**, but because the needed supplies are buried under many other crates, the crates need to be rearranged.
+
+The ship has a **giant cargo crane** capable of moving crates between stacks. To ensure none of the crates get crushed or fall over, the crane operator will rearrange them in a series of carefully-planned steps. After the crates are rearranged, the desired crates will be at the top of each stack.
+
+The Elves don't want to interrupt the crane operator during this delicate procedure, but they forgot to ask her **which** crate will end up where, and they want to be ready to unload them as soon as possible so they can embark.
+
+They do, however, have a drawing of the starting stacks of crates **and** the rearrangement procedure (your puzzle input). For example:
+
+```
+    [D]    
+[N] [C]    
+[Z] [M] [P]
+ 1   2   3 
+
+move 1 from 2 to 1
+move 3 from 1 to 3
+move 2 from 2 to 1
+move 1 from 1 to 2
+```
+
+In this example, there are three stacks of crates. Stack 1 contains two crates: crate `Z` is on the bottom, and crate `N` is on top. Stack 2 contains three crates; from bottom to top, they are crates `M`, `C`, and `D`. Finally, stack 3 contains a single crate, `P`.
+
+Then, the rearrangement procedure is given. In each step of the procedure, a quantity of crates is moved from one stack to a different stack. In the first step of the above rearrangement procedure, one crate is moved from stack 2 to stack 1, resulting in this configuration:
+
+```
+[D]        
+[N] [C]    
+[Z] [M] [P]
+ 1   2   3 
+```
+
+In the second step, three crates are moved from stack 1 to stack 3. Crates are moved **one at a time**, so the first crate to be moved (`D`) ends up below the second and third crates:
+
+```
+        [Z]
+        [N]
+    [C] [D]
+    [M] [P]
+ 1   2   3
+```
+
+Then, both crates are moved from stack 2 to stack 1. Again, because crates are moved **one at a time**, crate `C` ends up below crate `M`:
+
+```
+        [Z]
+        [N]
+[M]     [D]
+[C]     [P]
+ 1   2   3
+```
+
+Finally, one crate is moved from stack 1 to stack 2:
+
+```
+        [Z]
+        [N]
+        [D]
+[C] [M] [P]
+ 1   2   3
+```
+
+The Elves just need to know **which crate will end up on top of each stack**; in this example, the top crates are `C` in stack 1, `M` in stack 2, and `Z` in stack 3, so you should combine these together and give the Elves the message `CMZ`.
+
+**After the rearrangement procedure completes, what crate ends up on top of each stack?**
+
+## Part 2
+
+As you watch the crane operator expertly rearrange the crates, you notice the process isn't following your prediction.
+
+Some mud was covering the writing on the side of the crane, and you quickly wipe it away. The crane isn't a CrateMover 9000 - it's a **CrateMover 9001.**
+
+The CrateMover 9001 is notable for many new and exciting features: air conditioning, leather seats, an extra cup holder, and the **ability to pick up and move multiple crates at once.**
+
+Again considering the example above, the crates begin in the same configuration:
+
+```
+    [D]    
+[N] [C]    
+[Z] [M] [P]
+ 1   2   3 
+```
+
+Moving a single crate from stack 2 to stack 1 behaves the same as before:
+
+```
+[D]        
+[N] [C]    
+[Z] [M] [P]
+ 1   2   3 
+```
+
+However, the action of moving three crates from stack 1 to stack 3 means that those three moved crates **stay in the same order**, resulting in this new configuration:
+
+```
+        [D]
+        [N]
+    [C] [Z]
+    [M] [P]
+ 1   2   3
+```
+
+Next, as both crates are moved from stack 2 to stack 1, they **retain their order** as well:
+
+```
+        [D]
+        [N]
+[C]     [Z]
+[M]     [P]
+ 1   2   3
+```
+
+Finally, a single crate is still moved from stack 1 to stack 2, but now it's crate `C` that gets moved:
+
+```
+        [D]
+        [N]
+        [Z]
+[M] [C] [P]
+ 1   2   3
+```
+
+In this example, the CrateMover 9001 has put the crates in a totally different order: **`MCD`**.
+
+Before the rearrangement process finishes, update your simulation so that the Elves know where they should stand to be ready to unload the final supplies. **After the rearrangement procedure completes, what crate ends up on top of each stack?**
