There are N cities on a 2D plane. The coordinate of the i-th city is (x_i, y_i). Here (x_1, x_2, \dots, x_N) and (y_1, y_2, \dots, y_N) are both permuations of (1, 2, \dots, N).
For each k = 1,2,\dots,N, find the answer to the following question:
Rng is in City k. Rng can perform the following move arbitrarily many times:
How many cities (including City k) are reachable from City k?
Input is given from Standard Input in the following format:
N x_1 y_1 x_2 y_2 : x_N y_N
Print N lines. In i-th line print the answer to the question when k = i.

Rng can reach City 4 from City 3, or conversely City 3 from City 4.
