( 1849 ) D You Are Given a Tree PROGRAMMING data structures dp trees 2700

B'A tree is an undirected graph with exactly one simple path between each pair of vertices. We call a set of simple paths k -valid if each vertex of the tree belongs to no more than one of these paths (including endpoints) and each path consists of exactly k vertices. You are given a tree with n vertices. For each k from 1 to n inclusive find what is the maximum possible size of a k -valid set of simple paths. The first line of the input contains a single integer n ( 2 <= n <= 100 ,000 ) -- the number of vertices in the tree. Then following n - 1 lines describe the tree, each of them contains two integers v , u ( 1 <= v, u <= n ) -- endpoints of the corresponding edge. It is guaranteed, that the given graph is a tree. Output n numbers, the i -th of which is the maximum possible number of paths in an i -valid set of paths. One way to achieve the optimal number of paths for the second sample is illustrated in the following picture: '...
