Problem Statement

We have a tree with N vertices numbered 1 to N. The i-th edge in this tree connects Vertex a_i and b_i.
Additionally, each vertex is painted in a color, and the color of Vertex i is c_i. Here, the color of each vertex is represented by an integer between 1 and N (inclusive). The same integer corresponds to the same color; different integers correspond to different colors.
For each k=1, 2, ..., N, solve the following problem:

  • Find the number of simple paths that visit a vertex painted in the color k one or more times.

Note: The simple paths from Vertex u to v and from v to u are not distinguished.

Input

Input is given from Standard Input in the following format:
N
c_1 c_2 ... c_N
a_1 b_1
:
a_{N-1} b_{N-1}

Output

Print the answers for k = 1, 2, ..., N in order, each in its own line.

Constraints

  • $1 \leq N \leq 2 \times 10^5$
  • $1 \leq c_i \leq N$
  • $1 \leq a_i,b_i \leq N$
  • The given graph is a tree.
  • All values in input are integers.

Let P_{i,j} denote the simple path connecting Vertex i and j.
There are 5 simple paths that visit a vertex painted in the color 1 one or more times:
P_{1,1}\,,\,
P_{1,2}\,,\,
P_{1,3}\,,\,
P_{2,3}\,,\,
P_{3,3}
There are 4 simple paths that visit a vertex painted in the color 2 one or more times:
P_{1,2}\,,\,
P_{1,3}\,,\,
P_{2,2}\,,\,
P_{2,3}
There are no simple paths that visit a vertex painted in the color 3 one or more times.
