I remember when I once as a high schooler took a part of one nation-wide programming competition. I read instructions that were like we expect this output: "...". I assumed I need to output everything in quotes, so I tested my algorithms and happily submitted once I was sure they worked fine. I was pretty shocked when I got very bad score back - the issue was obviously I took it too literally and they actually didn't expect quotes; after the competition when I talked to organizers they re-ran the modified programs and I'd have ended up in 4th place... Well, tough luck.
