Problem 1 (80 points) Consider the following software architectures: Figure 1: Architecture 1 Figure 2: Architecture 2 Show the orders of module integration for the top-down and bottom-up integration approaches. Problem 2 (20 points) Consider the following system: Figure 3: System The system S has three input parameters X, Y, and Z. Assume that set D, a set of input test data values, has been selected for each of the input variables such that D(X)={ True, False },D(Y)={0,5}, and D(Z)={P,Q,R}. What is the total number of test cases for this system
