#D10469. Almost Same Distance
Almost Same Distance
Almost Same Distance
Let G be a simple graph. Let W be a non-empty subset of vertices. Then W is almost-k-uniform if for each pair of distinct vertices u,v ∈ W the distance between u and v is either k or k+1.
You are given a tree on n vertices. For each i between 1 and n, find the maximum size of an almost-i-uniform set.
Input
The first line contains a single integer n (2 ≤ n ≤ 5 ⋅ 10^5) – the number of vertices of the tree.
Then n-1 lines follows, the i-th of which consisting of two space separated integers u_i, v_i (1 ≤ u_i, v_i ≤ n) meaning that there is an edge between vertices u_i and v_i.
It is guaranteed that the given graph is tree.
Output
Output a single line containing n space separated integers a_i, where a_i is the maximum size of an almost-i-uniform set.

Output
4 4 2 1 1 1
Note
Consider the first example.
- The only maximum almost-1-uniform set is {1, 2, 3, 4}.
- One of the maximum almost-2-uniform sets is or {2, 3, 5}, another one is {2, 3, 4}.
- A maximum almost-3-uniform set is any pair of vertices on distance 3.
- Any single vertex is an almost-k-uniform set for k ≥ 1.
In the second sample there is an almost-2-uniform set of size 4, and that is {2, 3, 5, 6}.
