@championswimmer the codeclimate test renders ambiguous results, rest all tests have passed, please have a look

@AkshayCHD could you not move the lines that codeclimate are complaining about to their own method?

It seems to just be complaining that some code is similar (lines 207/235), which could be moved to a single method with parameters and that should fix it.

EDIT: I haven't actually looked at the code in its entirety so I'm not sure how feasible this is, hence my asking. Forgot to mention this part.

[AkshayCHD]

@alcha actually the problem is that the codes represent two cases of a switch case and although the codes look similar there are alot of case specific variables in each case. So if i create a common function i would have an overhead of checking again and again which case is it, which is not desired in my opinion. I could be wrong about it, I don't know for sure, but thank you for the suggestion.

[4lch4]

Ahhh, that makes sense then. No worries 😊
