A Conclusion of Exam 1&2

Before：This is my conclusion of the Exams twice a month.I will upd it once a month as a way to improve myself.

Score & Rank

Exam 1 : 130/300 4/39
Exam 2 : 30/300 26/39

You will see that I didn’t do a good job in Exam 2.I believe that at least I should get 130/300 with a rank of 9/39 in Exam 2,but something terrible happens.
I will explain it later.

Complication of Exam 1

Problem 1 is a model exercise of the Chunking Idea.

Problem 2 is quite easy.

Problem 3 talks about a new way of Matrix Compression called CSR.It’s also quite easy if you understand the meaning of the method.
