For C={c1,c2,c3} , T={ t12=0.5 , t13=0.9 , t21=1.5 , t23=1 , t31=2.1 , t32=0.7} when tij is the change ratio from coin i to j .
The answer is yes. (one possible change circle  t12 * t23 * t31=1.05 >1)

ok this is confusing, according to the assignment page the following input C={c1,c2},T={ t12=0.1} is legal and the algorithm should return yes.

but according to your example, the answer is no, can you clarify?

does it has to start in index i and finish in that same index (the original input)?

1) No, your input is not legal because you don't have a change ratio from c2 to c1. But if t21 > 10 then the algorithim should answer yes .
2) Yes, it should start and end at the same index .

thanks for the clarification, it is now more understandable.
