 # Trees and Sum of Distances

An undirected, connected tree with N nodes labelled 0…N-1 and N-1 edges are given.

The ith edge connects nodes A[i] and A[i] together.

Return an array of integers, ith index representes the sum of the distances between node i and all other nodes.

Input Format:

``````The first and the only argument has a 2-d array of integers of size N x 2, where nodes A[i] and A[i] are connected.
``````

Output Format:

``````Return an array of integers, where the ith index represents the answer as described in the problem statement.
``````

Constraints

``````1 <= A <= 10000
``````

For Example:

``````Input 1:
A = [[3, 1], [2, 1], [0, 2], [3, 4]]

Output 1:
[10, 6, 7, 7, 10]

Explanation 1:
dist(0, 1) = 2
dist(0, 2) = 1
dist(0, 3) = 3
dist(0, 4) = 4

Total sum of distances for Node 0 : 1 + 2 + 3 + 4 = 10.
