Currently I am learning about generating functions and some problems of this type requires polynomials operation such as multiplication and exponents. But I cannot figure out what template to use. There are some templates such as CP-algorithms but I cannot digest it because it includes so many libraries that I cannot remember to use in some competitions. So can someone give a easy to comprehend template for Polynomials.
Requirements:
FFT , NTT for mod like 998244353 and 1e9+7 .
Logarithm of polynomials .
Exponent of polynomials .
Hopefully someone can share the link.
Thank you.
