Problem Statement
We have a tree with $N$ vertices, numbered $1, 2, \dots, N$. The $i$-th edge $(1 \leq i \leq N-1)$ connects Vertex $A_i$ and Vertex $B_i$.
A boy E869120 found this tree and wants to write an integer in each vertex to surprise another boy square1001. For that, the following conditions need to be satisfied, where $E_i$ is the integer written on Vertex $i$.
Condition 1:
$E_i \geq 1$$(1 \leq i \leq N)$holds. Condition 2:$|E_i - E_j| \geq dist(i, j)$holds for every pair$(i, j)$$(1 \leq i < j \leq N)$. Condition 3: the value$\max(E_1, E_2, \dots, E_N)$should be minimized while satisfying Conditions 1 and 2.
Here, $dist(i, j)$ is:
- the length of the simple path (the path without repetition of the same vertex) from Vertex
$i$to$j$. - In other words, it is the value
$L$where the simple path is$q_0 \to q_1 \to q_2 \to \cdots \to q_L$($q_0 = i, q_L = j$).
Construct one way to write integers that surprises square1001.
Constraints
$2 \leq N \leq 200000$$1 \leq A_i < B_i \leq N$- The given graph is a tree.
- All values in input are integers.
Input
Input is given from Standard Input in the following format:
N
A_1 B_1
A_2 B_2
\vdots
A_{N-1} B_{N-1}
Output
Print a line containing integers $E_1, E_2, \cdots, E_N$ to write on the vertices, in this order, with space as separator.
If there are multiple ways to write integers that satisfy the conditions in the Problem Statement, any of them will be accepted.
