    Problem Description
    You are given a tree (an acyclic undirected connected graph) with N nodes. The tree nodes are numbered from 1 to N

    There are N - 1 edges numbered from 1 to N - 1.

    Each node has a value and each edge has a value. The initial value is 0.

    There are two kind of operation as follows:

    ● ADD1 u v k: for nodes on the path from u to v, the value of these nodes increase by k.

    ● ADD2 u v k: for edges on the path from u to v, the value of these edges increase by k.

    After finished M operation on the tree, please output the value of each node and edge.
     

    Input
    The first line of the input is T (1 ≤ T ≤ 20), which stands for the number of test cases you need to solve.

    The first line of each case contains two integers N ,M (1 ≤ N, M ≤105),denoting the number of nodes and operations, respectively.

    The next N - 1 lines, each lines contains two integers u, v(1 ≤ u, v ≤ N ), denote there is an edge between u,v and its initial value is 0.

    For the next M line, contain instructions “ADD1 u v k” or “ADD2 u v k”. (1 ≤ u, v ≤ N, -105 ≤ k ≤ 105)
     

    Output
    For each test case, print a line “Case #t:”(without quotes, t means the index of the test case) at the beginning.

    The second line contains N integer which means the value of each node.

    The third line contains N - 1 integer which means the value of each edge according to the input order.
     

    Sample Input
    2 4 2 1 2 2 3 2 4 ADD1 1 4 1 ADD2 3 4 2 4 2 1 2 2 3 1 4 ADD1 1 4 5 ADD2 3 2 4
     

    Sample Output
    Case #1: 1 1 0 1 0 2 2 Case #2: 5 0 0 5 0 4 0
