#P1588F. Jumping Through the Array
Jumping Through the Array
No submission language available for this problem.
Description
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 $p_j$.
Please, process all queries and print answers to queries of type $1$.
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 $i$, $j$ ($1 \le i, j \le n$).
For every first type query, print a single integer — the answer to this query.
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:
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 $a_1 + a_2 + a_3 + a_4 + a_5 = 6 + 9 + (-5) + 2 + (-1) = 11$.
