Function mod_reduce_string

pub fn mod_reduce_string(poly: &Polynomial, modulus: i64) -> Polynomial

The mod_reduce_string function applies modular reduction to the coefficients of a polynomial while optionally filtering out zero coefficients. This ensures the coefficients remain within the range defined by the modulus, preserving data integrity for string-based operations.

Description

Inputs:

• poly: A reference to the input Polynomial whose coefficients will be reduced and potentially filtered.
• modulus: An i64 value specifying the modulus for reduction.

Output: A new Polynomial object with coefficients reduced modulo the given value. Zero coefficients may be filtered out based on implementation.

Use Case: This function is useful in cryptographic workflows where strings are encoded as polynomials, ensuring the data fits within a finite field and remains concise.
