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 a consisting of n positive integers and queries to it. The queries can be of two types:
- Make a unit cyclic shift to the right on the segment from l to r (both borders inclusive). That is rearrange elements of the array in the following manner: a[l],a[l+1],...,a[r−1],a[r]→a[r],a[l],a[l+1],...,a[r−1].
- Count how many numbers equal to k are on the segment from l to r (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 n ( 1<=n<=105 ) — the number of elements of the array. The second line contains n integers a[1],a[2],...,a[n] ( 1<=a[i]<=n ).
The third line contains a single integer q ( 1<=q<=105 ) — the number of queries. The next q 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: 1 li′ ri′ . A query of the second type will be given in format: 2 li′ ri′ ki′ . All the number in input are integer. They satisfy the constraints: 1<=li′,ri′,ki′<=n .
To decode the queries from the data given in input, you need to perform the following transformations:
li=((li′+lastans−1) mod n)+1; ri=((ri′+lastans−1) mod n)+1; ki=((ki′+lastans−1) mod n)+1. Where lastans is the last reply to the query of the 2-nd type (initially, lastans=0 ). If after transformation li is greater than ri , you must swap these values.
输出格式
For each query of the 2-nd type print the answer on a single line.
