Using this prompt with DeepSeek

DeepSeek reasons in the open: it performs best when the prompt asks for the reasoning explicitly and separates it from the final answer, which is how this version is structured. Give it the goal and the constraints; let it think in steps before concluding.

Replace the bracketed placeholders — [PASTE CODE], [ERROR MESSAGE OR SYMPTOM], [WHAT YOU EXPECTED] — with your own details before pasting.
