Bodya and Sasha found a permutation $$$p_1,\dots,p_n$$$ and an array $$$a_1,\dots,a_n$$$. They decided to play a well-known "Permutation game".

A permutation of length $$$n$$$ is an array consisting of $$$n$$$ distinct integers from $$$1$$$ to $$$n$$$ in arbitrary order. For example, $$$[2,3,1,5,4]$$$ is a permutation, but $$$[1,2,2]$$$ is not a permutation ($$$2$$$ appears twice in the array), and $$$[1,3,4]$$$ is also not a permutation ($$$n=3$$$ but there is $$$4$$$ in the array).

Both of them chose a starting position in the permutation.

The game lasts $$$k$$$ turns. The players make moves simultaneously. On each turn, two things happen to each player:

If the current position of the player is $$$x$$$, his score increases by $$$a_x$$$.
Then the player either stays at his current position $$$x$$$ or moves from $$$x$$$ to $$$p_x$$$.

The winner of the game is the player with the higher score after exactly $$$k$$$ turns.

Knowing Bodya's starting position $$$P_B$$$ and Sasha's starting position $$$P_S$$$, determine who wins the game if both players are trying to win.

Input

The first line contains a single integer $$$t$$$ ($$$1\le t\le 10^4$$$) — the number of testcases.

The first line of each testcase contains integers $$$n$$$, $$$k$$$, $$$P_B$$$, $$$P_S$$$ ($$$1\le P_B,P_S\le n\le 2\cdot 10^5$$$, $$$1\le k\le 10^9$$$) — length of the permutation, duration of the game, starting positions respectively.

The next line contains $$$n$$$ integers $$$p_1,\dots,p_n$$$ ($$$1 \le p_i \le n$$$) — elements of the permutation $$$p$$$.

The next line contains $$$n$$$ integers $$$a_1,\dots,a_n$$$ ($$$1\le a_i\le 10^9$$$) — elements of array $$$a$$$.

It is guaranteed that the sum of values of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.

Output

For each testcase output:

"Bodya" if Bodya wins the game.
"Sasha" if Sasha wins the game.
"Draw" if the players have the same score.

Note

Below you can find the explanation for the first testcase, where the game consists of $$$k=2$$$ turns.

Turn	Bodya's position	Bodya's score	Bodya's move	Sasha's position	Sasha's score	Sasha's move
first	$$$3$$$	$$$0 + a_3 = 0 + 5 = 5$$$	stays on the same position	$$$2$$$	$$$0 + a_2 = 0 + 2 = 2$$$	moves to $$$p_2=1$$$
second	$$$3$$$	$$$5 + a_3 = 5 + 5 = 10$$$	stays on the same position	$$$1$$$	$$$2 + a_1 = 2 + 7 = 9$$$	stays on the same position
final results	$$$3$$$	$$$10$$$		$$$1$$$	$$$9$$$

As we may see, Bodya's score is greater, so he wins the game. It can be shown that Bodya always can win this game.
