ShishirShekhar / PolynomialConstantTermFinder

This project implements a simplified version of Shamir's Secret Sharing algorithm to find the constant term of a polynomial using Lagrange interpolation. Given a set of points encoded in a JSON format with different bases, this tool decodes the points, performs interpolation, and calculates the constant term.
