Range Query on a Tree

Write a program which manipulates a weighted rooted tree $T$ with the following operations:

• $add(v,w)$: add $w$ to the edge which connects node $v$ and its parent
  
• $getSum(u)$: report the sum of weights of all edges from the root to node $u$
  

The given tree $T$ consists of $n$ nodes and every node has a unique ID from $0$ to $n-1$ respectively where ID of the root is $0$. Note that all weights are initialized to zero.

Input

The input is given in the following format.

$n$
$node_0$
$node_1$
$node_2$
$:$
$node_{n-1}$
$q$
$query_1$
$query_2$
$:$
$query_{q}$

The first line of the input includes an integer $n$, the number of nodes in the tree.

In the next $n$ lines,the information of node $i$ is given in the following format:

ki c1 c2 ... ck

$k_i$ is the number of children of node $i$, and $c_1$ $c_2$ ... $c_{k_i}$ are node IDs of 1st, ... $k$th child of node $i$.

In the next line, the number of queries $q$ is given. In the next $q$ lines, $i$th query is given in the following format:

0 v w

or

1 u

The first integer represents the type of queries.'0' denotes $add(v, w)$ and '1' denotes $getSum(u)$.

Constraints

• All the inputs are given in integers
• $ 2 \leq n \leq 100000 $
• $ c_j < c_{j+1} $   $( 1 \leq j \leq k-1 )$
• $ 2 \leq q \leq 200000 $
• $ 1 \leq u,v \leq n-1 $
• $ 1 \leq w \leq 10000 $

Output

For each $getSum$ query, print the sum in a line.
