def remove_long_words(words):

"""Given a list of words, remove any that are longer

than four letters and return a new, shorter list.

>>> w = ['ten', 'one', 'seven', 'nine', 'fifteen']

>>> w = ['fifteen']

Let M be the product of two distinct prime numbers p1 and p2, and let a be an integer chosen so that the greatest common factor of a and M is 1.

By considering the value of a^(p1-1)(p2-1) modulo p1 and modulo p2, or otherwise, prove that a^(p1-1)(p2-1) ≡ 1 mod M.

An RSA Public Key system works with modulus 676873 which is the product of two primes. A message, represented by the number 3, is sent using the public exponent 17.

What is the corresponding encoded message?
