Description

• Mid2 exam accounts for 15% of your semester grade.
• This exam contains three problems. In order to reduce the possibility of traffic jam, the test cases of some problems are divided into several parts.
• The grade of your mid2 exam is computed as follows:
  Let P1 be 12261, P2 be 13910-13912, P3 be 13914-13916.
  Grade = Score(P1) + Score(P2) * 0.5 + Score(P3) * 0.5,
  where Score(Pi) is the number of testcases you earned for problem Pi.
• There are totally 15 points.

• {12261} --> {13910-13912} --> {13914-13916}
