力扣决定给一个刷题团队发LeetCoin作为奖励。同时，为了监控给大家发了多少LeetCoin，力扣有时候也会进行查询。

\n\n

 

\n\n

该刷题团队的管理模式可以用一棵树表示：

\n\n
    \n\t
  1. 团队只有一个负责人，编号为1。除了该负责人外，每个人有且仅有一个领导（负责人没有领导）；
    2. \n\t
  2. 不存在循环管理的情况，如A管理B，B管理C，C管理A。
    3. \n
\n\n

 

\n\n

力扣想进行的操作有以下三种：

\n\n
    \n\t
  1. 给团队的一个成员（也可以是负责人）发一定数量的LeetCoin；
    2. \n\t
  2. 给团队的一个成员（也可以是负责人），以及他/她管理的所有人（即他/她的下属、他/她下属的下属，……），发一定数量的LeetCoin；
    3. \n\t
  3. 查询某一个成员（也可以是负责人），以及他/她管理的所有人被发到的LeetCoin之和。
    4. \n
\n\n

 

\n\n

输入：

\n\n
    \n\t
  1. N表示团队成员的个数（编号为1～N，负责人为1）；
    2. \n\t
  2. leadership是大小为(N - 1) * 2的二维数组，其中每个元素[a, b]代表b是a的下属；
    3. \n\t
  3. operations是一个长度为Q的二维数组，代表以时间排序的操作，格式如下：\n\t
      \n\t\t
    1. operations[i][0] = 1: 代表第一种操作，operations[i][1]代表成员的编号，operations[i][2]代表LeetCoin的数量；
      2. \n\t\t
    2. operations[i][0] = 2: 代表第二种操作，operations[i][1]代表成员的编号，operations[i][2]代表LeetCoin的数量；
      3. \n\t\t
    3. operations[i][0] = 3: 代表第三种操作，operations[i][1]代表成员的编号；
      4. \n\t
    \n\t
    4. \n
\n\n

输出：

\n\n

返回一个数组，数组里是每次查询的返回值（发LeetCoin的操作不需要任何返回值）。由于发的LeetCoin很多，请把每次查询的结果模1e9+7 (1000000007)。

\n\n

 

\n\n

示例 1：

\n\n
输入：N = 6, leadership = [[1, 2], [1, 6], [2, 3], [2, 5], [1, 4]], operations = [[1, 1, 500], [2, 2, 50], [3, 1], [2, 6, 15], [3, 1]]\n输出：[650, 665]\n解释：团队的管理关系见下图。\n第一次查询时，每个成员得到的LeetCoin的数量分别为（按编号顺序）：500, 50, 50, 0, 50, 0;\n第二次查询时，每个成员得到的LeetCoin的数量分别为（按编号顺序）：500, 50, 50, 0, 50, 15.\n
\n\n

\"\"

\n\n

 

\n\n

限制：

\n\n
    \n\t
  1. 1 <= N <= 50000
    2. \n\t
  2. 1 <= Q <= 50000
    3. \n\t
  3. operations[i][0] != 3 时，1 <= operations[i][2] <= 5000
    4. \n
