题目描述
You are given two permutations $p$ and $q$ , consisting of $n$ elements, and $m$ queries of the form: $l_{1},r_{1},l_{2},r_{2}$ $(l_{1}<=r_{1}; l_{2}<=r_{2})$ . The response for the query is the number of such integers from $1$ to $n$ , that their position in the first permutation is in segment $[l_{1},r_{1}]$ (borders included), and position in the second permutation is in segment $[l_{2},r_{2}]$ (borders included too).
A permutation of $n$ elements is the sequence of $n$ distinct integers, each not less than $1$ and not greater than $n$ .
Position of number $v$ $(1<=v<=n)$ in permutation $g_{1},g_{2},...,g_{n}$ is such number $i$ , that $g_{i}=v$ .
A permutation of $n$ elements is the sequence of $n$ distinct integers, each not less than $1$ and not greater than $n$ .
Position of number $v$ $(1<=v<=n)$ in permutation $g_{1},g_{2},...,g_{n}$ is such number $i$ , that $g_{i}=v$ .
输入格式
The first line contains one integer $n\ (1<=n<=10^{6})$ , the number of elements in both permutations. The following line contains $n$ integers, separated with spaces: $p_{1},p_{2},...,p_{n}\ (1<=p_{i}<=n)$ . These are elements of the first permutation. The next line contains the second permutation $q_{1},q_{2},...,q_{n}$ in same format.
The following line contains an integer $m\ (1<=m<=2·10^{5})$ , that is the number of queries.
The following $m$ lines contain descriptions of queries one in a line. The description of the $i$ -th query consists of four integers: $a,b,c,d\ (1<=a,b,c,d<=n)$ . Query parameters $l_{1},r_{1},l_{2},r_{2}$ are obtained from the numbers $a,b,c,d$ using the following algorithm:
1. Introduce variable $x$ . If it is the first query, then the variable equals $0$ , else it equals the response for the previous query plus one.
2. Introduce function $f(z)=((z-1+x)\ mod\ n)+1$ .
3. Suppose $l_{1}=min(f(a),f(b)),r_{1}=max(f(a),f(b)),l_{2}=min(f(c),f(d)),r_{2}=max(f(c),f(d))$ .
