please solve the below question as the answer should be in the same format of the given function for the countinous one

DTFT:X(j)=x[n]ejnIDTFT:x[n]=21X(ej)ejnd Create the following MATLAB functions: - dtft which computes the discrete-time Fourier transform of a signal - idtft that computes the inverse discrete-time Fourier transform of a signal Test your functions by plotting the Fourier transform and the inverse Fourier transform of the following signal. Plot the magnitude of Fourier transform as a function of . Use plot(w,abs(Y)) to plot the Fourier transform and stem(n,y) to plot the original signal and the inverse of Fourier transform. Add a descriptive title for each plot and label all axes appropriately. Use subplot to create a grid of size 1 by 3 for your plots. x[n]=[n] Use a suitable range for n and
