Maybe that's where the disconnect comes from. For me understanding comes before doing. And coding for me is doing. There may be cases when I assumes that my understanding was complete and the feedback (errors during compiling and testing) told me I'm wrong, but that just triggers another round of research to seek understanding.

Puzzle solving is only for when information are not available (reverse engineering, closed systems,...) but there's a lot of information out there for the majority of tasks. I'm amazed when people spend hours trying to vibe code something, where they could spend just a few minutes reading about the system and comes up with a working solution (or find something that already works).
