Hello, Codeforces users. I started to learn NTT (i already know FFT and can implement it). But my code is not working for 998244353, but it works well for smaller modules, like 7340033 and 65537.
Here is my code: https://paste.ubuntu.com/p/QdKYCPMx3F/
P stands for power of 2. For example: 998244353 = 119 * 2 ^ 23 + 1. R stand for primitive root.
