"""# ### 谜题描述 You are given two permutations p and q, consisting of n elements, and m queries of the form: l1, r1, l2, r2 (l1 ≤ r1; l2 ≤ r2). 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 [l1, r1] (borders included), and position in the second permutation is in segment [l2, r2] (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 g1, g2, ..., gn is such number i, that gi = v. Input The first line contains one integer n (1 ≤ n ≤ 106), the number of elements in both permutations. The following line contains n integers, separated with spaces: p1, p2, ..., pn (1 ≤ pi ≤ n). These are elements of the first permutation. The next line contains the second permutation q1, q2, ..., qn in same format. The following line contains an integer m (1 ≤ m ≤ 2·105), 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 l1, r1, l2, r2 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 l1 = min(f(a), f(b)), r1 = max(f(a), f(b)), l2 = min(f(c), f(d)), r2 = max(f(c), f(d)). Output Print a response for each query in a separate line.
