One day he gets a new gal game named ''XX island''. There are n scenes
in that game, and one scene will be transformed to different scenes by choosing different options while playing the game. All the scenes form a structure like a rooted tree such that the root is exactly the opening scene while leaves are all the ending scenes.
Each scene has a value , and we use wi as
the value of the i-th
scene. Once Katsuragi entering some new scene, he will get the value of that scene. However, even if Katsuragi enters some scenes for more than once, he will get wi for
only once.
For his outstanding ability in playing gal games, Katsuragi is able to play the game k times
simultaneously. Now you are asked to calculate the maximum total value he will get by playing that game for k times.
denoting the number of test cases.
For each test case, the first line contains two numbers n,k(1≤k≤n≤100000),
denoting the total number of scenes and the maximum times for Katsuragi to play the game ''XX island''.
The second line contains n non-negative
numbers, separated by space. The i-th
number denotes the value of the i-th
scene. It is guaranteed that all the values are less than or equal to 231−1.
In the following n−1 lines,
each line contains two integers a,b(1≤a,b≤n),
implying we can transform from the a-th
scene to the b-th
scene.
We assume the first scene(i.e., the scene with index one) to be the opening scene(i.e., the root of the tree).
