You have decided to write a book introducing good restaurants. There are N restaurants that you want to introduce: Restaurant 1, Restaurant 2, ..., Restaurant N. Restaurant i is in city S_i, and your assessment score of that restaurant on a 100-point scale is P_i. No two restaurants have the same score.

You want to introduce the restaurants in the following order:
