Currently I am learning about generating functions and some problems of this type requires polynomials operation such as multiplication and exponents. But I can figure out what template to go for. There is some template such as CP-algorithms but I cannot digest it becaues it includes too many libraries and in 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.
