Virtual contest is a way to take part in past contest, as close as possible to participation on time. It is supported only ACM-ICPC mode for virtual contests.
If you've seen these problems, a virtual contest is not for you - solve these problems in the archive.
If you just want to solve some problem from a contest, a virtual contest is not for you - solve this problem in the archive.
Never use someone else's code, read the tutorials or communicate with other person during a virtual contest.

standard outputSerega 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?

Input

The first line contains integer *n* (1 ≤ *n* ≤ 10^{5}) — 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* ≤ 10^{5}) — 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 ≤ *l*'_{i}, *r*'_{i}, *k*'_{i} ≤ *n*.

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

Where *lastans* is the last reply to the query of the 2-nd type (initially, *lastans* = 0). If after transformation *l*_{i} is greater than *r*_{i}, you must swap these values.

Output

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