Problem Statement

There are N cities and M roads.
The i-th road (1≤i≤M) connects two cities a_i and b_i (1≤a_i,b_i≤N) bidirectionally.
There may be more than one road that connects the same pair of two cities.
For each city, how many roads are connected to the city?

Constraints

2≤N,M≤50

1≤a_i,b_i≤N

a_i ≠ b_i

All input values are integers.

Input

Input is given from Standard Input in the following format:

N M
a_1 b_1
:
a_M b_M

Output

Print the answer in N lines.
In the i-th line (1≤i≤N), print the number of roads connected to city i.

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

use std::io::stdin;

#[allow(dead_code)]
fn input_strs() -> Vec<char> {
    let mut s = String::new();
    match stdin().read_line(&mut s) {
        Ok(_) => s.chars().collect(),
        Err(_) => panic!("err"),
    }
}

#[allow(dead_code)]
fn input_ints() -> Vec<u64> {
    let mut st = String::new();
    match stdin().read_line(&mut st) {
        Ok(_) => st.split_whitespace().map(|s| s.parse().unwrap()).collect(),
        Err(_) => panic!("err"),
    }
}

#[allow(unused_variables)]
fn solve() {
    let l = input_ints();
    let n = l[0] as usize;
    let m = l[1] as usize;

    let mut city = vec![0; n];

    for _ in 0..m {
        let road = input_ints();
        let a = (road[0] - 1) as usize;
        let b = (road[1] - 1) as usize;
        city[a] += 1;
        city[b] += 1;
    }

    for c in city {
        println!("{}", c);
    }

}

fn main() {
    solve();
