Score : $200$ points

Problem Statement

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

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

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 ($1 \leq i \leq N$) should contain the identification number of the restaurant that is introduced $i$-th in the book.

The lexicographical order of the names of the three cities is kazan $<$ khabarovsk $<$ moscow. For each of these cities, the restaurants in it are introduced in descending order of score. Thus, the restaurants are introduced in the order $3,4,6,1,5,2$.
