It Was Just Too Impressive

"Professor He, the situation at hand is... It took my computer all night last night, but I still couldn't find anything..." Gu Nianzhi was getting a little frustrated. She had never encountered such a situation before.

He Zhichu coughed lightly, then said to Gu Nianzhi, "Nianzhi, I want to ask you, are you familiar with the programming language Prolog?"

"Prolog? Programming-In-Logic?" Gu Nianzhi didn't miss a beat. "I am, in fact. However, this programming language is not widely used, and is still in its experimental stages."

"And do you know why it is not widely used?" He Zhichu was like a professor trying to facilitate creative thinking for Gu Nianzhi. He spoke as if this was a lecture in a classroom.
