Problem 3. Dance Mooves

USACO 2021 January Contest, Gold

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

At first, all NN cows (2N1052\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 (1K21051\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=1Ki = 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+12KK+1 \ldots 2K, again in minutes 2K+13K2K+1 \ldots 3K, and so on, continuing in a cyclic fashion for a total of MM minutes (1M10181\le M\le 10^{18}). 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.

Note: the time limit per test case on this problem is twice the default.

INPUT FORMAT (input arrives from the terminal / stdin):

The first line contains integers NN, KK, and MM. Each of the next KK lines contains (a1,b1)(aK,bK)(a_1,b_1) \ldots (a_K, b_K) (1ai<biN1\le a_i<b_i\le N).

OUTPUT FORMAT (print output to the terminal / stdout):

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

After 77 minutes, the cows in increasing order of position are [3,4,5,2,1,6][3,4,5,2,1,6].

  • Cow 11 reaches positions {1,2,3,4,5}\{1,2,3,4,5\}.
  • Cow 22 reaches positions {1,2,3,4}\{1,2,3,4\}.
  • Cow 33 reaches positions {1,2,3}\{1,2,3\}.
  • Cow 44 reaches positions {2,3,4}\{2,3,4\}.
  • Cow 55 reaches positions {3,4,5}\{3,4,5\}.
  • Cow 66 never moves, so she never leaves position 66.

SCORING: Test cases 1-5 satisfy N100,K200N\le 100, K\le 200.Test cases 6-10 satisfy M=1018M=10^{18}.Test cases 11-20 satisfy no additional constraints.
