Consider the following problem: You are given a pointer to the root r of a binary tree, where each vertex v has pointers v. lc and v. rc to the left and right child, and a value Val (v) >0. The value NIL represents a null pointer, showing that v has no child of that type. You wish to find the maximum total sum of vertices of a subset with the following constraints: If v is in the subset, then the following vertices cannot be in the subset:
The parent of v
The children of v
The sibling of v (the other vertex that shares the same parent as v)
(You can assume that the tree is a full balanced binary tree with n vertices where n= 2^k -1) for some K>=1

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
