Hi there, just wanted to clarify some assumptions about the lab: 1. Can we assume that no 2 kiktil will have the same name? I'm assuming this will be the case as if 2 kiktils had the same name, it would make the get_cousin_dist() function impossible to do. 2. On the same line of thought, can we assume that the get_cousin_dist() will always receive valid parameters aka the same name will not be given for lhs_name and rhs_name? Or do we need to return something like (-1, 0).
