Q2. [20 points] Design and implement a recursive program to determine and print Nth line of Pascal's Triangle, as shown below. Each interior value is the sum of the two values above it. Hint: use an array to store the values on each line. 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 1 5 10 10 5 1 1 6 15 20 15 6 1 1 7 21 35 35 21 7 1 1 8 28 56 70 56 28 8 1 After executing your program, the IDE console window might look like as the following sample outputs: Which line number of Pascal's Triangle? 1 Line 1 of Pascal's Triangle: 1 Another (y/n)? y Which line number of Pascal's Triangle? 2 Line 2 of Pascal's Triangle: 1 1 Another (y/n)? y Which line number of Pascal's Triangle? 3 Line 3 of Pascal's Triangle: 1 2 1 Another (y/n)? y Which line number of Pascal's Triangle? 4 Line 4 of Pascal's Triangle: 1 3 3 1 Another (y/n)? y Which line number of Pascal's Triangle? 5 Line 5 of Pascal's Triangle: 1 4 6 4 1

Imagine a scenario where an e-commerce platform is managed by multiple teams, each responsible for different parts of the user journey — the product catalog, shopping cart, payments, and user accounts. As new features are added, the duration of the end-to-end tests grows significantly because these tests need to cover cross-team workflows, such as adding items to the cart, checking out, and applying discounts. The larger the scope of the end-to-end tests, the slower and more difficult they become to manage, making it harder to efficiently test these cross-functional flows. What strategies could be implemented to address this issue and streamline the testing process without compromising test coverage or quality?

Consider the following continuous time periodic signal $x(t)$ that has the Fourier series coefficient as below: $x(t) = \sum_{k=-\infty}^{\infty} a_k e^{j\omega_0 kt}$, where $a_0 = 0$ and $a_k = \frac{-2j\sin(\frac{k\pi}{2})\sin(\frac{k\pi}{2})}{\pi k}$. 1) (10 points) When $x(t)$ inputs to an ideal low pass filter with a cutoff frequency $\omega_c = 0.6\pi$ that has the following magnitude and phase response, provide the mathematical expression of the output $y_1(t)$. 2) (10 points) When $x(t)$ inputs to an ideal low pass filter with a cutoff frequency $\omega_c = 0.6\pi$ that has the following magnitude and phase response, provide the mathematical expression of the output $y_2(t)$. 3) (5 points) Determine the power AND energy of BOTH outputs $y_1(t)$ and $y_2(t)$.
