What are we supposed to do here?

I feel like this should be rated higher than a 7.

yeah, there's two conceptions. there's the Strict and General conceptions. Both are right, i guess. This kata uses the Strict definition.

ah, i see. 0 would be the first year of the first century. following that logic then, trailing zeros would be still the same century. i don't know though if in common thought that's true. fringe case due to language misconceptions! fringe case... Also what if year 0 is actually considered the last year of BC, and AD starts with year 1?

wouldn't 2000 be the 21st century? wouldn't 1999 be the last year of the 20th century? like any year ending 99 would be the last year for a century, and any year ending in 00 would be the start of a new century, is my understanding.

What's the largest number that will be tested? 3999?

Hmm, I may have it wrong. I need to check my algorithm, my apologies.

cool, thanks i will try the wildcard operator.

Can someone tell me how to import stream for java? I seem to be unable to do so. I am writing "import java.util.stream;" and that doesn't seem to work.

okay, thank. i must not have been importing stream correctly for java then

is stream available as part of the package for import in this kata?

are we allowed to use functional programming in this kata? i was unable to import stream and function. i am new to functional programming so perhaps i was just importing it and using the libraries wrong.

Can anyone recommend a great book on learning PostgreSQL? I need a good book on it that goes into a good deal of depth. Looking stuff up online is only getting me so far.
