After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Well, this is kinda a duh moment for me... I did an iteration version which is wildly unnecessary, if you see this one. If anyone is still wondering how it works, it uses integer division to round down to the nearest whole number before multiplying by the divisor to get the complement.
this doesnt seem to work on a calculator
Can someone explain this sorcery?
Y'all need to use parentheses.
The task implies that the string would contain only valid values. Therefore it's better to panic on an invalid value.
