题目描述
Vasya has a tree consisting of n vertices with root in vertex 1 . At first all vertices has 0 written on it.
Let d(i,j) be the distance between vertices i and j , i.e. number of edges in the shortest path from i to j . Also, let's denote k -subtree of vertex x — set of vertices y such that next two conditions are met:
- x is the ancestor of y (each vertex is the ancestor of itself);
- d(x,y)≤k .
Vasya needs you to process m queries. The i -th query is a triple vi , di and xi . For each query Vasya adds value xi to each vertex from di -subtree of vi .
Report to Vasya all values, written on vertices of the tree after processing all queries.
输入格式
The first line contains single integer n ( 1≤n≤3⋅105 ) — number of vertices in the tree.
Each of next n−1 lines contains two integers x and y ( 1≤x,y≤n ) — edge between vertices x and y . It is guarantied that given graph is a tree.
Next line contains single integer m ( 1≤m≤3⋅105 ) — number of queries.
Each of next m lines contains three integers vi , di , xi ( 1≤vi≤n , 0≤di≤109 , 1≤xi≤109 ) — description of the i -th query.
输出格式
Print n integers. The i -th integers is the value, written in the i -th vertex after processing all queries.

说明/提示
In the first exapmle initial values in vertices are 0,0,0,0,0 . After the first query values will be equal to 1,1,1,0,0 . After the second query values will be equal to 1,11,1,0,0 . After the third query values will be equal to 1,11,1,100,0 .
