+# Day 5: Supply Stacks (https://adventofcode.com/2022/day/5)
+# Conditions:
+# - The input represents two sections seperated by an empty line, crates section and rearrangement section
+# - Crates Section is a 9 by 9 table, with vertical stacks and horizontal levels; The bottom level describes a stack
+#   with numbers from 1 to 9; Other levels (8 of them) are filled with crates represented by capital letters surrounded
+#   by squared brackets; Lack of crate is represented by three empty spaces
+# - Rearrangement section consists of a list of instructions; An instruction has a syntax "move [number of crates] from
+#   [stack x] to [stack y]"
