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.
Constraints

- $2 \le N \le 2 \times 10^5$
- $1 \le a_i, b_i \le N$
- The given graph is a tree.
- $1 \le Q \le 2 \times 10^5$
- $t_i \in \{1, 2\}$

Input
Input is given from Standard Input in the following format:
$N$ $a_1$ $b_1$ $\vdots$ $a_{N-1}$ $b_{N-1}$ $Q$ $t_1$ $e_1$ $x_1$ $\vdots$ $t_Q$ $e_Q$ $x_Q$
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 $3$.
