Baalaaaaji R, when the question says least, its axiomatic that for the least value we consider the lowest possible value (which here is 0). So I am not sure if your notion of "multiple least " values make sense. There has to be one "least value", cuz you know... its least. (Correct me if I am wrong)

It's 17 ,when k=0 ,but in question it's not clearly whether first least or second least or third least so it can't be determined
