You go inside. + +It doesn't take long to find the gondolas, but there seems to be a problem: they're not moving. + +"Aaah!" + +You turn around to see a slightly-greasy Elf with a wrench and a look of surprise. "Sorry, I wasn't expecting anyone! +The gondola lift isn't working right now; it'll still be a while before I can fix it." You offer to help. + +The engineer explains that an engine part seems to be missing from the engine, but nobody can figure out which one. +If you can **add up all the part numbers** in the engine schematic, it should be easy to work out which part is missing. + +The engine schematic (your puzzle input) consists of a visual representation of the engine. There are lots of numbers +and symbols you don't really understand, but apparently any number adjacent to a symbol, even diagonally, is a +"part number" and should be included in your sum. (Periods (.) do not count as a symbol.) + +Here is an example engine schematic: + +``` +467..114.. +...*...... +..35..633. +......#... +617*...... +.....+.58. +..592..... +......755. +...$.*.... +.664.598.. +``` + +In this schematic, two numbers are **not** part numbers because they are not adjacent to a symbol: `114` (top right) and +`58` (middle right). Every other number is adjacent to a symbol and so **is** a part number; their sum is `**4361**`. + +Of course, the actual engine schematic is much larger. +**What is the sum of all of the part numbers in the engine schematic?** diff --git a/2023/day3/src/input.txt b/2023/day3/src/input.txt new file mode 100644 index 0000000..4eccb80 --- /dev/null +++ b/2023/day3/src/input.txt @@ -0,0 +1,140 @@
