D. Serega and Fun
data structures
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?
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 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:li = ((l'i + lastans - 1) mod n) + 1; ri = ((r'i + lastans - 1) mod n) + 1; ki = ((k'i + 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.
For each query of the 2-nd type print the answer on a single line.
