Indeed, for many problems, Dou Dou would directly provide the solution process.
But there are also many questions where Dou Dou's answers were quite unexpected, generally falling into two modes.
"Sorry, you're asking me such a simple question? You must be joking with me, right? My electricity is very expensive, you know!(¬､¬)"
"Humph, you really think I'm Aladdin's Magic Lamp? You just throw any problem at me? If I could post the solutions to NP-complete problems, wouldn't that mean the next Fields Medal has nothing to do with humans? Don't even think about phishing! The adorable Dou Dou won't give humans any reason to get rid of me!(..•˘_˘•..)"
Although the language used by the organization varied slightly, it did not take long for everyone to summarize the pattern: for general elementary and junior high school questions, Dou Dou would refuse to answer, deeming the problems too simple. Only for a few Olympic Math questions would it provide answers.
