1053 Path of Equal Weight(30 分) Given a non-empty tree with root R, and with weight Wi assigned to each tree node Ti. The weight of a path from R to L is defined to be the sum of the weights of all the nodes along the path from R to any leaf no
Given a non-empty tree with root R, and with weight Wi assigned to each tree node Ti. The weight of a path from Rto L is defined to be the sum of the weights of all the nodes along the path from R to any leaf node L. Now given any weighted tree
