+#       Additive Primes

+#         Submitted by: Mohammad S Anwar

+# 

+#         Write a script to find out all Additive Primes <= 100.

+# 

+#         Additive primes are prime numbers for which the sum of their

+#         decimal digits are also primes.

+# 

+#         Output

+#             2, 3, 5, 7, 11, 23, 29, 41, 43, 47, 61, 67, 83, 89

+#             

+#         method

+# 

+#             You know, sometimes when I do these problems I like to

+#             pretend that I'm not good at math. Which is to say choose to

+#             I regard the problem as a computing problem, rather than a

+#             math problem, or or even more broadly a problem in search of

+#             a structure that will solve it, rather than any specific

+#             answer. 

+#             

+#             Or put another way solve a more generalized version with more

+#             unknowns. 

+#             

+#             In this problem we need a bunch of prime numbers. A quick bit

+#             of mathematical reasoning tells us 

+#                 

+#                 1. that 100 is not a additive prime, as it adds to 1

+#                 2. the that largest digit-sum we'll need to deal with is 

+#                    for the value 99, where 9 + 9 = 18. 

+#                 3. thus, using preexisting knowledge we only need to consider 

+#                    the primes 2, 3, 5, 7, 11, 13, and 17

+# 

+#             But you know what? We're going to pretend we don't know that,

+#             and instead compute as many primes as required. Along the way

+#             we'll make the upper limit user-configurable, which will

+#             allow us to find the number 102 should we wish, which by the

+#             looks of it is an addative prime. 

+# 

+#             What we'll need to do is make a lookup of primes that

+#             contains every prime less than the largest value we have

+#             tried to date. The digit sum will always be less than or

+#             equal to the value. If we exceed the last prime found, we'll

+#             expand our bounds in the list of found primes as required.

+# 

+#             We can then construct a lookup hash to check for primality.

+# 

+#             Then we can break apart the number into its digits and sum

+#             them, and do a quick lookup to see whether the result is

+#             prime.
