## Problem Description

Alice and Bob are playing a game called ‘Gameia ? Gameia !’. The game goes like this :
\0. There is a tree with all node unpainted initial.
\1. Because Bob is the VIP player, so Bob has K chances to make a small change on the tree any time during the game if he wants, whether before or after Alice’s action. These chances can be used together or separate, changes will happen in a flash. each change is defined as cut an edge on the tree.
\2. Then the game starts, Alice and Bob take turns to paint an unpainted node, Alice go first, and then Bob.
\3. In Alice’s move, she can paint an unpainted node into white color.
\4. In Bob’s move, he can paint an unpainted node into black color, and what’s more, all the other nodes which connects with the node directly will be painted or repainted into black color too, even if they are white color before.
\5. When anybody can’t make a move, the game stop, with all nodes painted of course. If they can find a node with white color, Alice win the game, otherwise Bob.
Given the tree initial, who will win the game if both players play optimally?

### Input

The first line of the input gives the number of test cases T; T test cases follow.
Each case begins with one line with two integers N and K : the size of the tree and the max small changes that Bob can make.
The next line gives the information of the tree, nodes are marked from 1 to N, node 1 is the root, so the line contains N-1 numbers, the i-th of them give the farther node of the node i+1.

### Limits

$T≤100$
$1≤N≤500$
$0≤K≤500$
$1≤P_i≤i$

### Output

For each test case output one line denotes the answer.
If Alice can win, output “Alice” , otherwise “Bob”.

Bob和Alice玩游戏。

## 题解

Alice如果下叶子节点，Bob就必须下它上面的一个点。所以，如果总的点数位奇数个，显然Alice赢。

Bob只有把完美匹配的数隔成n/2 个部分，使每个部分点的个数为2，才可胜。
