Problem Statement

A company has N members, who are assigned ID numbers 1, ..., N.

Every member, except the member numbered 1, has exactly one immediate boss with a smaller ID number.

When a person X is the immediate boss of a person Y, the person Y is said to be an immediate subordinate of the person X.

You are given the information that the immediate boss of the member numbered i is the member numbered A_i. For each member, find how many immediate subordinates it has.

Constraints

2 \leq N \leq 2 \times 10^5

1 \leq A_i < i

Input

Input is given from Standard Input in the following format:

N
A_2 ... A_N

Output

For each of the members numbered 1, 2, ..., N, print the number of immediate subordinates it has, in its own line.

Sample Input 1

use proconio::{input, fastout};
use std::collections::HashMap;

#[fastout]
fn main() {
    input!{
        n:u32,
    }

    let mut a: HashMap<u32, u32> = HashMap::new();

    for _i in 2..n+1 {
        input!{
            ai:u32,
        }
        match a.get_mut(&ai) {
            Some(x) => {*x += 1;},
            None => {a.insert(ai, 1);},
        }
    }

    for i in 1..n+1 {
        match a.get(&i) {
            Some(x) => println!("{}", x),
            None => println!("{}", 0),
        }
    }
