SLOG Week9

    Week 9 is a busy week since I had prepared for the test 2 on Wednesday and I need to start working on assignment 2 right away. Test 2 seems easier than previous one. Unlike test 1, I have much more time left when I complete it. The root reason is that we don't need to write API this time. On assignment 2, all we need to do is to solve different type of puzzles. I found interesting on sudoku puzzle. After completing the body and try to run it, the solving time differs in a wide range. Sometimes it only takes few seconds to solve a sudoku, but nearly one minute will be taken to solve the same sudoku puzzle when I run second time. Anyway, I expect to complete the assignment right after the weekend to avoid rushing on the due day.
