题目描述

You are given two permutations pp and qq , consisting of nn elements, and mm queries of the form: l1,r1,l2,r2l_{1},r_{1},l_{2},r_{2} (l1<=r1; l2<=r2)(l_{1}<=r_{1}; l_{2}<=r_{2}) . The response for the query is the number of such integers from 11 to nn , that their position in the first permutation is in segment [l1,r1][l_{1},r_{1}] (borders included), and position in the second permutation is in segment [l2,r2][l_{2},r_{2}] (borders included too).

A permutation of nn elements is the sequence of nn distinct integers, each not less than 11 and not greater than nn .

Position of number vv (1<=v<=n)(1<=v<=n) in permutation g1,g2,...,gng_{1},g_{2},...,g_{n} is such number ii , that gi=vg_{i}=v .

输入格式

The first line contains one integer n (1<=n<=106)n\ (1<=n<=10^{6}) , the number of elements in both permutations. The following line contains nn integers, separated with spaces: p1,p2,...,pn (1<=pi<=n)p_{1},p_{2},...,p_{n}\ (1<=p_{i}<=n) . These are elements of the first permutation. The next line contains the second permutation q1,q2,...,qnq_{1},q_{2},...,q_{n} in same format.

The following line contains an integer m (1<=m<=2105)m\ (1<=m<=2·10^{5}) , that is the number of queries.

The following mm lines contain descriptions of queries one in a line. The description of the ii -th query consists of four integers: a,b,c,d (1<=a,b,c,d<=n)a,b,c,d\ (1<=a,b,c,d<=n) . Query parameters l1,r1,l2,r2l_{1},r_{1},l_{2},r_{2} are obtained from the numbers a,b,c,da,b,c,d using the following algorithm:

  1. Introduce variable xx . If it is the first query, then the variable equals 00 , else it equals the response for the previous query plus one.
  2. Introduce function f(z)=((z1+x) mod n)+1f(z)=((z-1+x)\ mod\ n)+1 .
  3. Suppose l1=min(f(a),f(b)),r1=max(f(a),f(b)),l2=min(f(c),f(d)),r2=max(f(c),f(d))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)) .

输出格式

Print a response for each query in a separate line.
