A Flask application runs solutions of [Project Euler][projecteuler] with GAE (Google App Engine).

1. prime_factors() return prime factors (can be used to identify prime) e.g. prime_factors(20) returns [2, 2, 5] prime_factors(3) returns [3] a prime special value prime_factors(0) returns [0] prime_factors(1) returns [1]

2. divisors() return all divisors, including itself e.g. divisors(220) returns [1, 2, 4, 5, 10, 20]

3. digits() return number of digits and ditis list e.g. digits(1092) returns [4, [1, 0, 9, 2]]

4. is_prime()

5. primes_less_than()

6. factorGenerator()

This repository comes with a simple setting making a Flask application work with GAE

There several solutions solved by C++ codes.
