Problem Statement
We have a tree with N vertices and N-1 edges, where the vertices are numbered $1, 2, \dots, N$ and the edges are numbered $1, 2, \dots, N-1. Edge i connects Vertices a_i$ and b_i.
Each vertex in the tree has an integer written on it. Let c_i be the integer written on Vertex i. Initially, c_i = 0.
You will be given Q queries. The i-th query, consisting of integers t_i, e_i, and x_i, is as follows:
- If t_i = 1: for each Vertex v reachable from Vertex a_{e_i} without visiting Vertex b_{e_i} by traversing edges, replace c_v with c_v + x_i.
- If t_i = 2: for each Vertex v reachable from Vertex b_{e_i} without visiting Vertex a_{e_i} by traversing edges, replace c_v with c_v + x_i.
After processing all queries, print the integer written on each vertex.
Input
Input is given from Standard Input in the following format:

Output
Print the values $c_1, c_2, \dots, c_N$ after processing all queries, each in its own line.

In the first query, we add 1 to each vertex reachable from Vertex 1 without visiting Vertex 2, that is, Vertex 1.
In the second query, we add 10 to each vertex reachable from Vertex 4 without visiting Vertex 5, that is, Vertex 1, 2, 3, 4.
In the third query, we add 100 to each vertex reachable from Vertex 2 without visiting Vertex 1, that is, Vertex 2, 3, 4, 5.
In the fourth query, we add 1000 to each vertex reachable from Vertex 3 without visiting Vertex 2, that is, Vertex 3.
