A Growing Tree
Description
You are given a rooted tree with the root at vertex $1$, initially consisting of a single vertex. Each vertex has a numerical value, initially set to $0$. There are also $q$ queries of two types:
- The first type: add a child vertex with the number $sz + 1$ to vertex $v$, where $sz$ is the current size of the tree. The numerical value of the new vertex will be $0$.
- The second type: add $x$ to the numerical values of all vertices in the subtree of vertex $v$.
After all queries, output the numerical value of all of the vertices in the final tree.
The first line contains a single integer $T$ ($1 \leq T \leq 10^4$) — the number of test cases. The descriptions of the test cases follow.
The first line of each test case contains a single integer $q$ ($1 \leq q \leq 5 \cdot 10^5$) — the number of queries.
The following $q$ lines can fall into two cases:
- The first type of query: The $i$-th line contains two integers $t_i$ ($t_i = 1$), $v_i$. You need to add a child with the number $sz + 1$ to vertex $v_i$, where $sz$ is the current size of the tree. It is guaranteed that $1 \leq v_i \leq sz$.
- The second type of query: The $i$-th line contains three integers $t_i$ ($t_i = 2$), $v_i$, $x_i$ ($-10^9 \leq x_i \leq 10^9$). You need to add $x_i$ to all numerical values of vertices in the subtree of $v_i$. It is guaranteed that $1 \leq v_i \leq sz$, where $sz$ is the current size of the tree.
It is guaranteed that the sum of $q$ across all test cases does not exceed $5 \cdot 10^5$.
For each test case, output the numerical value of each vertex of the final tree after all queries have been performed.
Input
The first line contains a single integer $T$ ($1 \leq T \leq 10^4$) — the number of test cases. The descriptions of the test cases follow.
The first line of each test case contains a single integer $q$ ($1 \leq q \leq 5 \cdot 10^5$) — the number of queries.
The following $q$ lines can fall into two cases:
- The first type of query: The $i$-th line contains two integers $t_i$ ($t_i = 1$), $v_i$. You need to add a child with the number $sz + 1$ to vertex $v_i$, where $sz$ is the current size of the tree. It is guaranteed that $1 \leq v_i \leq sz$.
- The second type of query: The $i$-th line contains three integers $t_i$ ($t_i = 2$), $v_i$, $x_i$ ($-10^9 \leq x_i \leq 10^9$). You need to add $x_i$ to all numerical values of vertices in the subtree of $v_i$. It is guaranteed that $1 \leq v_i \leq sz$, where $sz$ is the current size of the tree.
It is guaranteed that the sum of $q$ across all test cases does not exceed $5 \cdot 10^5$.
Output
For each test case, output the numerical value of each vertex of the final tree after all queries have been performed.
