This chapter summarizes the advantages and disadvantages of the linear table sequential storage structure. Before summing up, let's discuss the time complexity of the execution method of the linear table sequential storage structure: Store, read:

The question should be understood in this way: 0 after the DfT (FFT is a fast DFT algorithm), in fact, the formula has not changed, the change is only the frequency domain terms (such as: 0 before the FFT calculation is m*2*pi/m at the frequency

This openness of this way has certain limitations, through the efforts can be overcome. It also has a certain superiority. Unlike previously used memory searches and local modifications, this approach can be modified not only locally, but also
