using opCmp

[Jaehunt]

Hi, I tried to compare two sets by opCmp, but I couldn't get 
correct outputs.

Does anyone help me?


I have same sets of set S1 = [1,2,3] and S2 = [1,2,3].

Output of S1<S2 should be false because S1 is not a proper subset.

However, S1<=S2 should be true because S1 is a subset of S1.


I can't make a difference between two sets by if statements, so I 
can't make different output.

Does any have a idea for it?

Thank you.
