How to Recognize an Error-Correcting Code
The problem that's trying to solve the way that it does it is inspired by how FFT works. If you're using Reet's Almond code, so polynomials, you could very well have that your message gets encoded into a straight line. So in that case, you do know that point is where the bit flip happened. This is the error. And it should have been on the pretty line. Because it's complicated enough. It would be almost probabilistically impossible that you'd have a wrong polynomial that only misses that spot. The purpose of FFTs is something else. I kind of forget what are the- what is the purpose of a fast
