[Rosettacode] sum of powers conjecture

[bearophile via Digitalmars-d-learn]

I've translated the C++ entry to D as third D entry, but it's not 
a good translation, I've just converted iterators to pointers 
instead of using ranges (the resulting speed is acceptable). 
You're welcome to improve it:
