1. (10 points) Write pseudocode for the tree-based approach to summing an array we discussed in class Suggestions for how to organize this are given in Exercises 1.3 and 1.4 at the end of the chapter. Note that your code should work even when the number of cores is not a power of two. (Though I do suggest that you figure it out for the power-of-two case and then (slightly) modify your solution as needed for the more general case.) 1.
