Guidebook

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:

• The restaurants are arranged in lexicographical order of the names of their cities.
• If there are multiple restaurants in the same city, they are arranged in descending order of score.

Print the identification numbers of the restaurants in the order they are introduced in the book.

Constraints

• 1 ≤ N ≤ 100
• S is a string of length between 1 and 10 (inclusive) consisting of lowercase English letters.
• 0 ≤ P_i ≤ 100
• P_i is an integer.
• P_i ≠ P_j (1 ≤ i < j ≤ N)

Input

Input is given from Standard Input in the following format:

N S_1 P_1 : S_N P_N

Output

Print N lines. The i-th line (1 ≤ i ≤ N) should contain the identification number of the restaurant that is introduced i-th in the book.
