Given a tree with IN nodes connected by N-1 edges, rooted at node 1, each edge in the tree is assigned a value, which can be either positive, negative, or zero. Your task is to calculate, for each node, the smallest total sum of edge values that can be obtained on a simple path from that particular node to any leaf node in the tree
Notes:
A simple path is a path in a tree that does not have repeating vertices.
A node that does not have any child node is called a leaf node
Input format
The first line contains a single integer T, which denotes the number of test cases.
For each test case:
The first line contains IN denoting the number of vertices in the tree.
The following IN-1 lines contain 3 space-separated integers, u, v, and w indicating that there is an edge between vertices u & tv, and this edge has value w.
Output format For each test case, print N integers in a new line, where the the integer depicts the smallest total sum of edge
