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.

import Data.Array.IO
import Control.Monad

main = do
  [n, m] <- map read . words <$> getLine :: IO [Int]
  input <- map (map read . words) . lines <$> getContents :: IO [[Int]]
  memo <- newArray (1, n) 0 :: IO (IOUArray Int Int)
  foldM memoize memo input
  ans <- getElems memo
  putStr $ unlines . map show $ ans

memoize :: IOUArray Int Int -> [Int] -> IO (IOUArray Int Int)
memoize memo [i, j] = do
  ii <- readArray memo i
  jj <- readArray memo j
  writeArray memo i (ii+1)
  writeArray memo j (jj+1)
  return memo
