题目描述

You are given an array b1,b2,,bnb_1, b_2, \ldots, b_n .

An anonymous informant has told you that the array bb was obtained as follows: initially, there existed an array a1,a2,,ana_1, a_2, \ldots, a_n , after which the following two-component operation was performed kk times:

  1. A fixed point ^{\dagger} xx of the array aa was chosen.
  2. Then, the array aa was cyclically shifted to the left ^{\ddagger} exactly xx times.

As a result of kk such operations, the array b1,b2,,bnb_1, b_2, \ldots, b_n was obtained. You want to check if the words of the anonymous informant can be true or if they are guaranteed to be false.

^{\dagger} A number xx is called a fixed point of the array a1,a2,,ana_1, a_2, \ldots, a_n if 1xn1 \leq x \leq n and ax=xa_x = x .

^{\ddagger} A cyclic left shift of the array a1,a2,,ana_1, a_2, \ldots, a_n is the array a2,,an,a1a_2, \ldots, a_n, a_1 .

输入格式

Each test contains multiple test cases. The first line contains an integer tt ( 1t1041 \le t \le 10^4 ) — the number of test cases. The description of the test cases follows.

The first line of each test case contains two integers n,kn, k ( 1n21051 \le n \le 2 \cdot 10^5 , 1k1091 \le k \le 10^9 ) — the length of the array bb and the number of operations performed.

The second line of each test case contains nn integers b1,b2,,bnb_1, b_2, \ldots, b_n ( 1bi1091 \le b_i \le 10^9 ) — the elements of the array bb .

It is guaranteed that the sum of the values of nn for all test cases does not exceed 21052 \cdot 10^5 .

输出格式

For each test case, output "Yes" if the words of the anonymous informant can be true, and "No" if they are guaranteed to be false.

说明/提示

In the first test case, the array aa could be equal to [3,2,3,4,3][3, 2, 3, 4, 3] . In the first operation, a fixed point x=2x = 2 was chosen, and after 22 left shifts, the array became [3,4,3,3,2][3, 4, 3, 3, 2] . In the second operation, a fixed point x=3x = 3 was chosen, and after 33 left shifts, the array became [3,2,3,4,3][3, 2, 3, 4, 3] . In the third operation, a fixed point x=3x = 3 was chosen again, and after 33 left shifts, the array became [4,3,3,2,3][4, 3, 3, 2, 3] , which is equal to the array bb .

In the second test case, the array aa could be equal to [7,2,1][7, 2, 1] . After the operation with a fixed point x=2x = 2 , the array became [1,7,2][1, 7, 2] . Then, after the operation with a fixed point x=1x = 1 , the array returned to its initial state [7,2,1][7, 2, 1] . These same 22 operations (with x=2x = 2 , and x=1x = 1 ) were repeated 4949 times. So, after 100100 operations, the array returned to [7,2,1][7, 2, 1] .

In the third test case, it can be shown that there is no solution.
