Xue Xi looked at the comments with a cold expression. "Fire the questions."
Someone really posted a question on the screen.
"Choose from five different colors to give the areas A, B, C, and D colors. The rules state that each area can have only one color applied, and the neighboring areas can't be applied with that same color. How many color combinations can be applied? Note: ABCD is one of the four areas in the field."
Xue Xi had just finished reading the question when she blurted out, "260 combinations."
The comment section got filled with question marks, and there were also people who accused her of playing around.
Xue Xi frowned. "I think it's also up to you guys to provide the answers to the questions."
"Sure, wait for me to open the book."
"F*ck, I can't take this lying down. I must reduce her spirit! Wait for me to find a question!"
