为什么我没有使用循环表的预期结果?

I am creating a code complexity measuring tool for a academic purpose. this is the method function. all the method return type,primitive data type parameters,composite data type parameters are awarded 1 point. complexity due to method is the addition of the earlier mentioned points.all these things divided into columns of a table. (i tried to summarized the specification as much as i can. please if it is not clear check this link. it is a half a page specification for this function https://gofile.io/d/Xme6Cb). i implemented the method function but i am getting wrong points in the tables. can someone please suggest what i should do. i m sorry the code is bit long and i tried to keep it to the minimal but i can't find out where the exact problem is. I have commented // -------- Weight due to return type - Begin -------- when i commented this loop i am getting 0 for all the columns. but when i uncomment this i am getting unexpected points for the table. i tried to fix this. but i had no luck. can someone please suggest me what i should do, and i am sorry if i couldn't keep the question to the minimal. i am stuck with this, any help is appreciated. Thank you!
