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 C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;

class program
{
    static void Main(string[] args)
    {
        string[] inputs = Console.ReadLine().Split();
        int N = int.Parse(inputs[0]);
        int M = int.Parse(inputs[1]);

        int[,] map = new int[N, N];

        for(int i = 0; i < M; i++)
        {
            inputs = Console.ReadLine().Split();
            int p = int.Parse(inputs[0]) - 1;
            int q = int.Parse(inputs[1]) - 1;
            map[p, q]++;
            map[q, p]++;
        }
        for(int i = 0; i < N; i++)
        {
            int ans = 0;
            for(int j = 0; j < N; j++)
            {
                ans += map[i, j];
            }
            Console.WriteLine(ans);
        }
    }
}
