Part 3/8:
On day three of Advent of Code, the streamer encounters a puzzle involving a gondola lift station. Here, they are faced with a missing engine part that needs to be identified by summing up part numbers associated with symbols in a given schematic. The challenge calls for parsing a visual representation of the machine's engine to find the total sum of all part numbers adjacent to specific symbols. The streamer expresses frustration yet determination to tackle the problem logically.
