@lei_cui, you’re correct. The answer or explanation for the code test is not included as part of the challenge. On the other hand, the challenge note in the lesson walks you through how to approach the problem and encourages you to apply your problem-solving abilities to produce a solution. As a result, you’ll have to translate the puzzle’s logic into a working code solution on your own. Good luck!
Happy learning at Educative.
