Twitter API - get users which are common in my following and followers list

I am developing a twitter API

I am using REST API using ruby Oath GEM

I need to get all users which开发者_StackOverflow社区 are common in my following and followers list.

What api can i use?

Thanks Sreeraj

Quite easy! Just perform a !diff between the two lists.

In other words, get both lists, and iterate over each entry/person, remove the differences, and viola!
