There were 30 people in the second round of the competition, and only the top 15 would make it to the final round.
What Oswald meant was that they must solve both problems before the first 15 names appeared on the board in order to win.
It's unknown how much time the first 15 competitors would take to solve the competition problem. In other words, they must solve two problems in an unknown time limit.
This was a test of one's mind.
Qiao Yue was very calm as she accepted Oswald's challenge.

Qiao Yue had a different solution. YQ was the one who had told her about it and they had studied it for a while.

"My computer is suddenly running very slow."
