You are given an array of integers $a$ of size $n$ and a permutation $p$ of size $n$. There are $q$ queries of three types coming to you:
- For given numbers
$l$and$r$, calculate the sum in array$a$on the segment from$l$to$r$:$\sum\limits_{i=l}^{r} a_i$. - You are given two numbers
$v$and$x$. Let's build a directed graph from the permutation$p$: it has$n$vertices and$n$edges$i \to p_i$. Let$C$be the set of vertices that are reachable from$v$in this graph. You should add$x$to all$a_u$such that$u$is in$C$. - You are given indices
$i$and$j$. You should swap$p_i$and$p_j$.
The graph corresponding to the permutation $[2, 3, 1, 5, 4]$.
Please, process all queries and print answers to queries of type $1$.
Input
The first line contains a single integer $n$ ($1 \le n \le 2 \cdot 10^5$) — the size of the array and permutation.
The second line contains $n$ integers $a_1, a_2, \ldots, a_n$ ($-10^8 \le a_i \le 10^8$).
The third line contains $n$ distinct integers $p_1, p_2, \ldots, p_n$ ($1 \le p_i \le n$).
The fourth line contains a single integer $q$ — the number of queries ($1 \le q \le 2 \cdot 10^5$).
Next $q$ lines contain description of queries. The $i$-th of them starts with an integer $t_i$ ($1 \le t_i \le 3$) — the query type.
- If
$t_i = 1$, then the$i$-th line also contains two integers$l$,$r$($1 \le l \le r \le n$). - If
$t_i = 2$, then the$i$-th line also contains two integers$v$,$x$($1 \le v \le n$,$-10^8 \le x \le 10^8$). - If
$t_i = 3$, then the$i$-th line also contains also two integers$i$,$j$($1 \le i, j \le n$).
Output
For every first type query, print a single integer — the answer to this query.
Note
In the first example:
The graph corresponding to the initial permutation.
There are $6$ queries.
- The sum on the segment from
$1$to$5$is$a_1 + a_2 + a_3 + a_4 + a_5 = 6 + 9 + (-5) + 3 + 0 = 13$. - If we start from
$1$, we can reach$\{1, 2, 3\}$. After this query$a$is:$[7, 10, -4, 3, 0]$. - The sum on the segment from
$1$to$5$is$a_1 + a_2 + a_3 + a_4 + a_5 = 6 + 9 + (-5) + 3 + 0 = 16$. - After this query
$p = [4, 3, 1, 5, 2]$.
The graph corresponding to the new permutation. - If we start from
$2$, we can reach$\{1, 2, 3, 4, 5\}$. After this query$a$is:$[6, 9, -5, 2, -1]$. - The sum on the segment from
$1$to$5$is$a_1 + a_2 + a_3 + a_4 + a_5 = 6 + 9 + (-5) + 2 + (-1) = 11$.
