Summary:

When I first started this topic, I did not understand the teacher's meaning, completely irrelevant. Later saw the class of students and teachers of the chat record, just know that they want to biased. But still do not know from where to start, later refer to Jerrick classmate do, have a little idea but still not clear. Later saw the Yu-yu teacher and the teacher said, with a little inspiration. Due to the deadline for homework, the first thing to do, and then slowly improve it, see so cumbersome code I was drunk. I hope the teacher can guide
