Fast Fourier Transform (FFT) for Polynomial Multiplication
FFT is a powerful algorithm for efficiently multiplying large polynomials. It significantly outperforms the naive approach of polynomial multiplication, offering asymptotic complexity of O(n log n) compared to O(n^2). This makes it a valuable tool for problems involving polynomial manipulation and signal processing.
