This project is a solution for the Hashira Placements coding assignment.

1. The program first reads a JSON input file.
2. Each root is stored with a base and a value.
3. The root is converted into a decimal integer using the base information.
4. Only the first k roots are selected, because k = m + 1 is sufficient for a polynomial of degree m.
5. The polynomial is then constructed by multiplying factors of the form (x - root).
6. The program finally prints:
   • The polynomial in an expanded, human-readable form.
   • The list of coefficients, from constant term to highest power of x.
