题目描述
Consider every tree (connected undirected acyclic graph) with n vertices ( n is odd, vertices numbered from 1 to n ), and for each 2≤i≤n the i -th vertex is adjacent to exactly one vertex with a smaller index.
For each i ( 1≤i≤n ) calculate the number of trees for which the i -th vertex will be the centroid. The answer can be huge, output it modulo 998244353 .
A vertex is called a centroid if its removal splits the tree into subtrees with at most (n−1)/2 vertices each.
输入格式
The first line contains an odd integer n ( 3≤n<2⋅105 , n is odd) — the number of the vertices in the tree.
输出格式
Print n integers in a single line, the i -th integer is the answer for the i -th vertex (modulo 998244353 ).

说明/提示
Example 1 : there are two possible trees: with edges (1−2) , and (1−3) — here the centroid is 1 ; and with edges (1−2) , and (2−3) — here the centroid is 2 . So the answer is 1,1,0 .
Example 2 : there are 24 possible trees, for example with edges (1−2) , (2−3) , (3−4) , and (4−5) . Here the centroid is 3 .
