PLEASE SHOW FULL STEPS. THANKS

a. Calculate the 4-point DFT of the sequence x[n] = {1, 1,2,3} . [6 points) b. Apply circular flip on x[n] and calculate its DFT. Comment on the result. (7 + 2 points] c. Apply circular shift on x[n] by one sample (i.e. x[(n 1)4]) and calculate its DFT. Comment on the result. [8 + 2 points] Note: you can use Matlab to speed-up calculation, but DO NOT use the FFT function. Include your code if you are using Matlab
