-phase electric currents. To allow the robot to work at three-phase currents, you may need a large-capacity, expensive converter that converts DC to AC power, or a wall outlet with a limited working range. You may not plan to use an AC motor unless your robot is fixed, just like a robot or a robot platform. If you are not planning to move the robot platform around like a puppy or something else...

A permission tree puts K robots from the root node to obtain the minimum weights and values of all nodes.
Ideas:
1. dp [u] [I] indicates placing an I robot on the subtree of the root node to traverse the minimum weight required by the subtree.
2. the key lies in the understanding of dp [u] [0]. It means that 0 robots are stuck in the sub-tree where u is the
