I've a custom rest route (based on the original Zend_Rest_Route) to allow certain custom rest routes.

Every time a post involves Python code, it has the Python tag AND the Python version tag that suits the version of Python that the post is using.
I think that is a little repetitive, and we should either:

Could you please help framing a logic to generate 3 substrings from a string suhc that sum of 2 substrings contains 3rd substring. String contains only integers. for ex:
str1 = "14711" // gives true as s1=4, s2=7 , s3=11
str2 = "14721" // true , s1=14, s2=7, s3=21
Thanks and Regards,
