Yesterday, we made a qualifying round for Tsinghua. Shen Da, Liang laoda, and Xiao cross each handled a single question, and almost fell out of 60. I did B and F, where F is about the number of reverse orders. The complexity is that the worst

I'm bored with it .. In fact, the key to this question is not the method of reverse order, because it is also possible to use brute force. To give a sequence with the length of n (n I use array a [0 ~ N-1] to store raw data. You only need to find

Use merge sort to find reverse order pairs and use merge sort to reverse order In reverse order, it is generally effective to use brute force solutions, but the time complexity of O (n2) is unacceptable. However, there is a seemingly irrelevant
