3107.Serega and Fun

Time Limit: 1s Memory Limit: 256MB

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] \rightarrow 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?

Input Format(From the terminal/stdin)

The first line contains integer n (1 \le n \le 105) - the number of elements of the array. The second line contains n integers a[1],a[2],...,a[n] (1 \le a[i] \le n).

The third line contains a single integer q (1 \le q \le 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 l'i r'i. A query of the second type will be given in format: 2 l'i r'i k'i. All the number in input are integer. They satisfy the constraints: 1 \le l'i,r'i,k'i \le n.

To decode the queries from the data given in input, you need to perform the following transformations:
li=((l'i+lastans-1)modn)+1;ri=((r'i+lastans-1)modn)+1;ki=((k'i+lastans-1)modn)+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.

Output Format(To the terminal/stdout)

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