Sure, the monks are here to write wonderful programs for free at the request of each and everyone and we don't even ask the applicants to show they have made any effort in trying to do it themselves.

Isn't that a bit of a strange request from someone whose e-mail address is hosted at a company which writes on their website:

what we do
Everstream enables the world’s largest digital service providers to mine, transform, warehouse, and analyze usage data from their interactive platforms.

One would think that such programs are daily fare for people of Everstream.

But since we are in a good mood, we will give you some free pointers to start your own research: hashes; angle bracket operator; while-loop;

BTW: asking a similar question two times in a row will not get you an answer any faster (you can re-open and update your original node if necessary) and will not particualrly enamour you with the Monks here.
