题目描述

Serega loves fun. However, everyone has fun in the unique manner. Serega has fun by solving query problems. One day Fedor came up with such a problem.

You are given an array aa consisting of nn positive integers and queries to it. The queries can be of two types:

  1. Make a unit cyclic shift to the right on the segment from ll to rr (both borders inclusive). That is rearrange elements of the array in the following manner: a[l],a[l+1],...,a[r1],a[r]a[r],a[l],a[l+1],...,a[r1].a[l],a[l+1],...,a[r-1],a[r]→a[r],a[l],a[l+1],...,a[r-1].
  2. Count how many numbers equal to kk are on the segment from ll to rr (both borders inclusive).

Fedor hurried to see Serega enjoy the problem and Serega solved it really quickly. Let's see, can you solve it?

输入格式

The first line contains integer nn ( 1<=n<=1051<=n<=10^{5} ) — the number of elements of the array. The second line contains nn integers a[1],a[2],...,a[n]a[1],a[2],...,a[n] ( 1<=a[i]<=n1<=a[i]<=n ).

The third line contains a single integer qq ( 1<=q<=1051<=q<=10^{5} ) — the number of queries. The next qq lines contain the queries.

As you need to respond to the queries online, the queries will be encoded. A query of the first type will be given in format: 11 lil'_{i} rir'_{i} . A query of the second type will be given in format: 22 lil'_{i} rir'_{i} kik'_{i} . All the number in input are integer. They satisfy the constraints: 1<=li,ri,ki<=n1<=l'_{i},r'_{i},k'_{i}<=n .

To decode the queries from the data given in input, you need to perform the following transformations:

li=((li+lastans1) mod n)+1; ri=((ri+lastans1) mod n)+1; ki=((ki+lastans1) mod n)+1.l_{i}=((l'_{i}+lastans-1) mod n)+1; r_{i}=((r'_{i}+lastans-1) mod n)+1; k_{i}=((k'_{i}+lastans-1) mod n)+1. Where lastanslastans is the last reply to the query of the 2-nd type (initially, lastans=0lastans=0 ). If after transformation lil_{i} is greater than rir_{i} , you must swap these values.

输出格式

For each query of the 2-nd type print the answer on a single line.
