CF1891F 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.
Input Format
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 Format
For each test case, output the numerical value of each vertex of the final tree after all queries have been performed.
Explanation/Hint
In the first case, the final tree with the assigned numerical values will look like this:
