Problem Statement

Takahashi is a teacher responsible for a class of N students.

The students are given distinct student numbers from 1 to N.

Today, all the students entered the classroom at different times.

According to Takahashi's record, there were A_i students in the classroom when student number i entered the classroom (including student number i).

From these records, reconstruct the order in which the students entered the classroom.

Constraints

1 \le N \le 10^5

1 \le A_i \le N

A_i \neq A_j (i \neq j)

All values in input are integers.

Input

Input is given from Standard Input in the following format:

N
A_1 A_2 \ldots A_N

Output

Print the student numbers of the students in the order the students entered the classroom.

Sample Input 1

3
2 3 1

Sample Output 1

3 1 2

First, student number 3 entered the classroom.

Then, student number 1 entered the classroom.

Finally, student number 2 entered the classroom.

Sample Input 2

5
1 2 3 4 5

Sample Output 2

1 2 3 4 5

Sample Input 3

8
8 2 7 3 4 5 6 1

Sample Output 3

8 2 4 5 6 7 3 1

Solution in Rust (1.15.1) (judge verdict: Accepted)

use std::io::BufRead;
use std::str::FromStr;

struct Student {
    seq: i32,
    num: i32
}

fn main() {
    let stdin = std::io::stdin();
    let mut t = Tokenizer::new(stdin.lock().lines().map(|x| x.unwrap()));

    let n: i32 = t.take();
    let mut h: Vec<Student> = Vec::new();
    for i in 1 .. n+1 {
        h.push( Student { seq: i, num: t.take() } );
    }
    h.sort_by(|a,b| a.num.partial_cmp(&b.num).unwrap() );
    for i in h.iter() {
        print!( "{} ", i.seq );
    }
    println!("");
