### Task 3

Draw the four-point FFT (Fast Fourier Transform) signal-flow diagram, and use it to solve for the DFT (Discrete Fourier Transform) of the sequence \( x(n) = \{1, 2, 2, 1\} \).

Instructions:
1. Begin by creating the signal-flow diagram for a four-point FFT.
2. Utilize this diagram to compute the DFT of the given sequence.

In this task, students are expected to visualize the FFT process and use it to transform the input sequence into its frequency components. Understanding the flow and how each stage processes the signals is key to mastering FFT computations.
