Just in case somebody missed it: we have wonderful girls in Arpa’s land.

Arpa has a rooted tree (connected acyclic graph) consisting of n vertices. The vertices are numbered 1 through n, the vertex 1 is the root. There is a letter written on each edge of this tree. Mehrdad is a fan of Dokhtar-kosh things. He call a string Dokhtar-kosh, if we can shuffle the characters in string such that it becomes palindrome.

$\text{[math]}$

He asks Arpa, for each vertex v, what is the length of the longest simple path in subtree of v that form a Dokhtar-kosh string.

Input

The first line contains integer n (1 ≤ n ≤ 5·10⁵) — the number of vertices in the tree.

(n - 1) lines follow, the i-th of them contain an integer p_i + 1 and a letter c_i + 1 (1 ≤ p_i + 1 ≤ i, c_i + 1 is lowercase English letter, between a and v, inclusively), that mean that there is an edge between nodes p_i + 1 and i + 1 and there is a letter c_i + 1 written on this edge.

Output

Print n integers. The i-th of them should be the length of the longest simple path in subtree of the i-th vertex that form a Dokhtar-kosh string.
