Shanks tonelli algorithm

WebbA simple implementation of the Tonelli-Shanks algorithm to compute a square root in Z/pZ where p is prime. It could probably be made quite faster by using a faster pow_mod function instead of the recursive one and also by trying to avoid some of the modulus calculations. · GitHub Instantly share code, notes, and snippets.
