### The Fast Fourier Transform (FFT) is one of the most fundamental numerical algorithms. It computes the Discrete Fourier Transform (DFT) of an n-dimensional signal in O(nlogn) time. The algorithm plays a central role in several application areas, including signal pro-cessing and audio/image/video compression. It is also a fundamental subroutine in integer multiplication and encoding/decoding of

- The DFT can be reduced from exponential time with the Fast Fourier Transform algorithm. One wonders if the DFT can be computed faster: Does another computational procedure -- an algorithm -- exist that can compute the same quantity, but more efficiently.
