Suppose we are given an n-node rooted tree T, such that each node v in T is given a weight w(v) R(R is positive real number). An independent set of T is a subset S of the nodes of T such that no node in S is a child or parent of any other node in S. Design an efficient dynamic programming algorithm to find the maximum-weight independent set of the nodes in T, where the weight of a set of nodes is simply the sum of the weights of the nodes in that set. For this question, we need to write a pseudocode for your algorithm and show its running time
