Should have just given the formula for center of mass,

mass1position1 + mass2position2 ... / mass1 + mass2 ...

or at least a better hint

Lua translation !

When I log out my return statement, I get [ 'one', 'three', 'five', 'four' ]

However, I get this error: expected undefined to deeply equal [ 'one', 'three', 'five', 'four' ]

Could someone please help me understand what is going on?

Weird, weird Kata! But still not bad)

Please check and approve!

you won't see that in the funnel given, but if you alter the arguments, you have to find something yourself that will signify an empty space (e.g. |, \, zz)

anything works

Fixed.

For the random tests in python, the wording in the message you get when it is incorrect is switched (ex: when it is supposed to say None should equal ['four'], it says ['four'] should equal None)
