Problem

Farmer John's cows are showing off their new dance mooves!

At first, all NN cows (2≤N≤1052\le N\le 10^5) stand in a line with cow ii in the iith position in line. The sequence of dance mooves is given by KK (1≤K≤2⋅1051\le K\le 2\cdot 10^5) pairs of positions (a1,b1),(a2,b2),…,(aK,bK)(a_1,b_1), (a_2,b_2), \ldots, (a_{K},b_{K}). In each minute i=1…Ki = 1 \ldots K of the dance, the cows in positions aia_i and bib_i in line swap. The same KK swaps happen again in minutes K+1…2KK+1 \ldots 2K, again in minutes 2K+1…3K2K+1 \ldots 3K, and so on, continuing indefinitely in a cyclic fashion. In other words,

  • In minute 11, the cows at positions a1a_1 and b1b_1 swap.
  • In minute 22, the cows at positions a2a_2 and b2b_2 swap.
  • ...
  • In minute KK, the cows in positions aKa_{K} and bKb_{K} swap.
  • In minute K+1K+1, the cows in positions a1a_{1} and b1b_{1} swap.
  • In minute K+2K+2, the cows in positions a2a_{2} and b2b_{2} swap.
  • and so on ...

For each cow, please determine the number of unique positions in the line she will ever occupy.

Input

The first line contains integers NN and KK. Each of the next KK lines contains (a1,b1)…(aK,bK)(a_1,b_1) \ldots (a_K, b_K) (1≤ai<bi≤N1\le a_i<b_i\le N).

Output

Print NN lines of output, where the iith line contains the number of unique positions that cow ii reaches.
